go with diamond or wiseco
you need to decide what heads you are using and what chamber they are so you will know what kind of dish on the pistons you need to get to a good compression ratio for boost
you will see alot of guys run around 9.5 to 1 on their street cars so they have good throttle response and then use meth if you need it to get higher boost
on a good intercooled setup with 9.5 to 1 comp. ratio you shouldnt have any problems running 12-14 lbs without meth maybe more with a good tune

Yeah I think I'm going to go with Diamond. How big of a dish should I go with and what heads would you guys recommend. I'm kinda a noob when it comes the boost motor part.

alot of guys run the 317 truck heads,it doesnt matter too much seeing as how you will be forcing air through them
if you are going to be wanting 18+lbs of boost you may want a good aftermarket head with a thick deck
it all depends on how deep your pockets are
if you are on a tight budget go with the 317 heads,that will give you around the 9.5 to 1 comp ratio with flat top pistons then you can get the dished pistons to go a little lower if you would like
as stated earlier high boost and pump gas dont mix to well so if you are going to want much more than 16-18lbs i would lower the compression down in the 8.5 to 1 range
people are doing 16lbs all day with a little meth on 9.5 to 1

317 heads will be fine for 16 psi.. arp head bolts... it all depends.
what size turbo are you planning on running?
you need to provide some more info on what you plan on using your setup for.

I have a T-76 turbo right now. Plan on upgrading in a year. So far I would like to do a stock cubed LS1. Money Isn't to much of an issue. I will have meth. The turbo set-up is based off of an OFI kit. Fuel system has been proven for 1000+WHP. I'm either going to run E-85 or just pump gas. Its going to have a stage 3 FLT tranny. Going to need some help on picking a stall for that. And as far as the cam I am looking for the Hannible Lector cam or something with a very lopey idle with decent street manners. Anything else you guys need to know ask.
