My setup is as follows... stock ls block(b18b), b16 pr3 pistons, arp rod bolts, stock ls rods, gsr head, full port and polish done by local shop, oem head gaskets, arp head studs, toda valve trainand stock gsr valves. Question, what cams can i run? I know the dome on the pr3's arent too dramatic compared to ctr's. And from my calculation my CR should be around 11.2-11.5. I wanted to run s2 pro 1's but im worried about the p2v clearence. Im not too educated in the ways of valve to piston clearence thats why im asking advice from my fellow HT members! lol, any advice or past experience is appreciated.

 

Pro1s will work nicely with your setup. P2V valve should be okay, but you should clay the motor. Pretty simple and will give you your options on which camshafts you can run, but IMO, you should be okay

 

Any other input? Considering buddy club spec4's, or the brian crower stage 3's. Any advice or experience?

 

Clay the motor is your best bet! Take some time to do it and you'll have your peace of mind, but I think you'll be fine.

 

Ahh hell! You talked me into it!

 

its not hard to clay a motor. spend the hour and you will have your peace of mind like jv88 said
