Head selection

Bench Racer · 11-06-2015, 06:07 PM

Adger, my brother David ran a 624 head super stock combination several years ago. I think it was a 1981 Chevy 350/175hp engine with a Q-jet. It was a very stout piece in SS but had some "high dollar" heads on it. Not sure how they would flow in stocker trim. The numbers were 462624.

624 was the lightweight version of the 882. Very prone to cracks and many cores only had a 1.72 intake.

Sm valve 624 came on L48--- large valve on L82--- 75 and later heads have an EXTRA exhaust manifold bolt hole ---VERY prone to cracking ---check around coolant holes and between valve seats--FED 387
