the p8r head does have an 84mm chamber, i personally belive it has like a 43-44 cc chamber compared to the 45cc LS head and it flows 20 cfm more than a regular LS head stock for stock. however you shouldnt buy one untill i do since they are super rare and i got dibs...

but yeah again im with jdavis "grab a good set of cams, boost that biotch, rev to 8 grand, and call it a day."

i talked to my machinest. he said 200 thats including old guides pressed out and new ones pressed in and a 3 angl valve job and overbore if i decided to go with bigger valves. im thinking 1mm over with nitride coated stainless valves. also gonna run tit retainers and dual valve springs. ill just give it a mild pnp with the summit porting kit. im not gona gut the ---- outta it, just match the ports with the exhaust mani and clean up casting marks and debur.
my goal is about 400-450 with my built bottom end with an sc61 on pump gas.

3G Piglude intake valves are 33mm, and have the correct stem and overall length. Bowl needs worked to suit a 2mm increase in size.

Supertech makes "stock" sized replacements for those engines.

From a flow aspect, go with Omni's valves. Brad Z says they flow the best on the market.

I was looking at KMS. They have an awful nice valvetrain deal, considering it for D-series. If they trade blockguard from the combo for valveguides they have my business.
