i have some complete stock 5.3 heads coming in to be ported. i also have a broken valvespring. can any part of the stock 5.3 valvetrain work on my 5.7 LS1, or will i have to make a post in the newb mod mistakes soon after doing that.

I searched and got alot of stuff bout the LS2 and LS7, and the newb information guide, read that no luck.

thank you.

 

5.3L, 5.7L (ls1, ls6), and 6.0L (lq9) heads are interchangable along with all their components
btw stock valvesprings of any kind will not work with any aftermarket cam...or should i say are not recommended...i'd just go ahead and get the prc dual spring kit to go on those heads, unless you are running the stock cam

 

so can i just disassemble my stock 5.3 heads and put the valvetrain from those on my stock 5.7 heads with a stock cam and be good? cuz im prob just gonna do a cam later on where ill just buy a cam kit. is pushrod length any different cuz i have some hardened steel pushrods to go in there toothat are stock length. 7.4"

thanks again.

 

can anyone second this?

 

Think you need 7.350" pushrods with 5.3 heads, maybe?

 

nah not that, i was wondering if i could use the stock valvetrain from the 5.3 heads on my 5.7 heads. stock cam stock heads.

but thanks anyways, i appreciate your input
