porting heads question

302's are a good head

Go with 1.88 and 1.60 valves a good valve job also. Open up the pushrod pinch as much as possible. I totally removed it but didnt really pick up much flow for the work done.

Knock the edge off the SSR and give it a smooth radius and that will pick up the higher lifts.

With just a bowl job, 1.84 intake valve and opening up the pinch mine went 217 cfm @ 440 lift without touching the ssr ending up at 132 cc intake runner volume

Currently they are 228 @ 500 and 140 cc runner with 1.88 valve.

Hysteric
