AFR 185 SBF Heads with 58cc combustion chambers

Summit RacingSummit Racing Verified Purchase

excellent quality castings and a head to be reckoned with. Was missing rocker arm studs and guide plates other than that they were worth every penny. I'm glad I went with AFR instead of TFS!

AFRs cost a little more but all the valve heights and spring pads were spot on. The only reason I didn't rate 5 stars is because over half the guide plates had burrs that had to be ground to get the rocker tips to center over the valve tip. ...read more
