im thinking of adding new heads for my 408 but i wanna do a combination of heads nd intake can somebody lead me too a good direction thanks in advance

 

L92 heads with l92 truck intake or l76 car intake...flow very well for the price!! they are rectangular port ...not cathedral...and the intakes are 90mm
--or some cnc'd 317's with the new FAST lsxrt intake for trucks$$

 

ur talking about da 102 lsxrt??

 

nope just the stock truck intake of the l92 i think thats what he meant and yea those l92 should do the work!

 

AFR 225's

 

Dont mess with the L92 heads .... I have run the WCCH 245cc heads for two years without a single headgasket problem pushing the 925-1025 rwhp They use all Factory rockers, No special intakes and valve covers.. Along with top notch service and a Very nice product they have held up well and taken all the beating i can throw at them ... In fact My WCCH motor has been in my truck for 2 years about 75 dyno pulls and at least 225 track passes with 5500 HARD miles... and I have never removed the intake,exhaust manifolds or valve covers since the day the motor was installed in the truck Call Richard or look at his website and tell him Casey sent ya

 

Yes, in my second suggestion...NO ONE can answer you until we know how much you would like to spend , and what intake you will be running...

 

whats his number or website i can look at dis heads
