Depending on the valve timing, you might have some PTV clearance issues. What cam are you putting in the 370?

 

P to V has nothing to do with your quench area. Dirt generally the aftermarket 6.125 rod with the correct pistons will put you at +.008 +/- .001, I would order the run-of-the-mill .04 cometic and go on down the road since its a common size and thickness.

 

thats the gasket i had in mind last night

cam is the same cam i got now 230 226 597 563

 

you need to find you a set of 317's or 243's and scrap those 241's. Those are the crappiest gen 3 heads out thier.

 

Correct me if I'm wrong, but doesn't TTY bolts mean they are suppose to be one time use bolts?

I thought after they are stretched to the proper torque specs that it is not good to try and re-use them. Just would suck to spend all of this money and run into problems cause of some head bolts.

 

ARP bolts arent TTY so you can reuse them. Stock bolts are TTY.

 

Cool I didn't realize that. Thanks.

 

Definitley get some better heads

 

the heads have been ported..but i dont know what they would flow..how much milling does it take to get 317 heads to 66-67cc's and what length push rod would i need?

 

heres 2 pics of the mahle pistons and h beam rods i got
