Cylinder head discussion 340 with stock above deck pistons

Not with a stick car with 235 drag radials. He is dropping the clutch at 2500, bogging the engine down and driving out to a 2.0 60 foot. He needs to come out higher and manage the clutch slip with a bias ply slick and get it down to at least a 1.70 60 foot and the car should run in the 12's. Clutch management, either a lot of foot control or a Clutch Tamer or a Soft-Loc clutch. He needs to slip the clutch and keep the engine at or above peak torque until the rpm's and tire speed match up. Think of using the clutch like a high stall torque converter.

Yes. But the OP will listen to every rail bird out there thats never had a stick.

The snubber needs to find a different home. If he doesn't have double adjustable shocks and has single adjustable shocks...no one can tune those.

The least he needs is a clutch tamer. He's going to have a hell of a time leaving on a two step with just using his leg unless he has 10 years of practice at it and even then not having a ST or better yet a soft lock clutch.

In fact I'd say wait on the heads and get a clutch and shocks. Far better money spent on that than heads.

But what do I know???
