ls3/l76 questions hey guys i've just recently gotten a 402 it currently has prc 5.3's and and ms3 with the bbk ssi intake manifold. im looking at getting more power on a (budget). So i sat down today and made a list of the things i plan on purchasing when i get back from deployment. i found a set of heads i will be getting next month from scoggin dickey, they are ls3 gm stock clyinder heads. with the l76 intake. i just have a few questions about these items.
1) what exactly do i need to makes these heads work like will the stock ls1 7.400 push rods work? what about the rockers? i was told the exhaust rockers will work but the intake is offset is that true if so what should i do
2) my over all goal with this car is 500rwhp on motor and around 650-675 on bottle will the stock ls3 heads befine?
3) for the l76 i know i need and ls3 fuel rail which im not sure where to find them at? but if i purchase and ls3 fuel rail set up will i need new injectors or will the katech spacers work?
im really trying to stick to my budget so any input would help me so much thank you for your time...

SDPC has the rockers. The stock Ls3 ones will work, or have them rebuilt with better bearings. You'll need better springs then the stock ones to make the power ur talking about. The injectors will need to have a projected tip to fit the manifold.http://www.fuelairspark.com/WhatsNew...stechsheet.pdf
The spacers I'm not sure about. The stock fuel rail that you have may work. The heads are not going to make that power with out some work and cam designed for them. Contact FTI .Ed Curtis is the man PM me with any questions. You'll need some large tube headers. The MS3 will need to go.
