ARP High Performance Series Cylinder Head Bolt Kits 134-3601

I believe I would upgrade to studs because of the horsepower

BYRON L from SC answered on September 11, 2017

These will be fine

JAMES R from SC answered on September 08, 2017

These bolts will work, use good head gaskets. I like MLS.

DENNIS from OH answered on September 10, 2017

The bolts should withstand the pressures created by increased cylinder pressures of higher compression. If the engine is used for racing applications then studs should be used.

JOSEPH from WI answered on September 07, 2017

These will work easily at that hp level. The threads in the block should always be checked. That is the weak point.

MIKE from WA answered on September 20, 2017

Hello yes these bolts will work just fine .
Tho if using aluminum heads I would use studs as you will get a more even holding across your head .
And if this is a motor you will be taking apart frequently studs would be more user friendly . And if u decide to use bolts make sure u check thread depth don't want them bottoming out before proper. Torque hope this helps

DENNIS from OR answered on September 18, 2017

These will work fine

WILLIE from MS answered on September 18, 2017

Use studs,and all ways them out before you take the head off.

LEVI H from NC answered on September 19, 2017

yes,these will work.if you are running a turbo with alot of boost or more than 150 shot of nitrous,go with the studs to be safe.

TODD from MI answered on September 17, 2017

I will typically use head bolts for any engines that I build that are not forced induction. Once we go to FI we use studs. These would be fine for an engine making 600/600. What I would say though, money being no object, I would ALWAYS recommend studs over bolts, you will get better clamping. I have used 100's of sets of ARP hardware, you cannot go wrong!

NICHOLAS from TN answered on September 08, 2017

I have used them on high performance builds in the past, and had no problems....

KENNETH from NH answered on September 07, 2017

Upgrade to Studs... a motor like that, you probably really don't want to even chance a head gasket, or ripping threads.

SARAH from ID answered on September 08, 2017

Arp is the best fasteners around and they would prob work but wirh that much hp and torque i would run with there head studs

CODY from VA answered on September 20, 2017

upgrade to studs

ROBERT E from FL answered on October 13, 2017

I'm sure they would. But if you are running lots of boost or N2O NOS then studds might be the best.

ROBERT G from IL answered on September 11, 2017

Using the washers “equalizes” the torque of the nut on the stud for a consistent stretch of the stud. You can get away with not using a washer sometimes in clearance situations like under an exhaust manifold runner but you should use them on every location that will allow.

JAMES P from MI answered on November 24, 2017

With washers

RENEAL from TX answered on December 29, 2017

yes you do.

TEDD from IL answered on November 23, 2017

Use the washers

PATRICK from VA answered on January 23, 2018

Use the washers...make sure the inner chamfered edge is up, towards the bolt head. Check every one during installation.

KENNETH from WA answered on November 22, 2017

With the washers.

JOE from United States answered on November 23, 2017

ARP fasteners were designed to be used with washers it helps to distribute the clamping load of the bolt evenly.

STEVE from TN answered on November 18, 2017

Using the washers will help with a more accurate torque reading. Reccommend using.

WILLIAM from MN answered on November 29, 2017

These bolts are designed to use the washer. I would not recommend using them without the washers especially on a stock engine. Seat pressure and bolt length could cause problems.

MIKE from WA answered on November 24, 2017

With washers, beveled side up.

GREGORY from CA answered on November 18, 2017

Use the washers that came h the new bolts. Be sure to lube both sides of the washers to get an accurate torque reading.

CHRIS from PA answered on November 25, 2017

I put vortec heads on my 70s block and i used these bolts with the washers, Didn't have any problems.

CAMERON from OR answered on December 01, 2017

If the kit was ordered for your engine specifically I imagine ARP would have not included the washers if un necessary...follow ARP instructions. Have depended on them for decades without a fastener problem ever..

JOHN F from NC answered on November 25, 2017

With washers.

THOMAS L from PA answered on November 20, 2017

Yes, all 23* SBCs

JAMES R from SC answered on November 08, 2017

Yes,these bolts will fit this engine with the cast iron vortec heads

GEORGE A from CA answered on November 09, 2017

No

MARK from MO answered on November 12, 2017

Yes this is the right part number for ur motor.

MARTIN from CA answered on November 11, 2017

Yes small block Chevy they will work and they are a great product

JOHN from KY answered on October 22, 2017

Yes it should I have 3 motors with them and they are in a 1991 5.7 vorteck

HAYDEN from ND answered on November 04, 2017

I ordered the AArp bolts for my 95 Chevy 350. They fit from 1987 to 1995. I do not know if these will fit for your project. Call summit

SCOTT from IN answered on November 15, 2017

All gen 1 small block chevys take the same thread and length bolts including the vortec so yes

KENNETH from NY answered on October 29, 2017

Yes

BILLY L from MS answered on November 05, 2017

Yes they do.

TRACY from PA answered on November 12, 2017

yes it does

ELTON from WA answered on November 15, 2017

Yes, this kit works for any small block gen 1 chevy.

GLENDON from VA answered on October 22, 2017

it should I have them on a 93 350 vortec

MILTON from TX answered on November 07, 2017

Heck ya! Bolt them bad boys up!

RYAN from FL answered on November 08, 2017

Yes I have heard and seen guys reuse these head bolts

SCOTT from IN answered on October 15, 2017

Yes they are reusable and perfectly safe to do so

WES from NV answered on October 14, 2017

I would not suggest reusing these. They are designed to be torqued down and have a specific amount of stretch. Similar to a torque to yield bolt but not exactly.

CODY from CO answered on October 11, 2017

Yes. I always clean them good before reuse.

MIKE from WA answered on October 20, 2017

Yes just measure and check for stretch

WILLIE from MS answered on October 18, 2017

A lot of people reuse a second or third time
If I was building a monster motor I would replace
But a motor with out hi compression u should be just fine
Hope this helps

DENNIS from OR answered on October 17, 2017

Yes these head bolts are reuseable,unlike tork to yeild bolts these do not strech.

STEVE from TN answered on October 20, 2017

Yes
