On a 1992 Silverado 5.7 TBI, using these heads in combination with Comp Cams # 1412-16 rocker arms, Edelbrock push rods # 9629, and matching Edelbrock camshaft & lifter Kit # 3702 will I need to use tall valve covers or will the stock work?

What rocker arms and pushrods would work best with these heads? And these heads are for a 93 tbi 350 c1500

Asked by TRACY on October 22, 2018


Yes, these are the Cylinder Heads for the 1987-1995 TBI engines, you can re-use the stock rocker arms, or maybe Comp Cams # 1412-16, which are reasonably priced, and the Push Rods are Edelbrock # 9629, hardened for use with the Guide Plates that come on these cylinder heads....FYI... matching camshaft & lifter Kit # 3702 is for the same year span TBI....

Do not fit stock valve covers

heads will have to be machined on valve cover rail, to wide. valve covers will have to be modified at bolt stanchions to clear head bolt washers. greatly disappointed at response from summit.
