Question about heads??? 317 or what?
 

I just got a LQ4 engine and I would like to get some more power of it with a small budget.

I want to put on it a car style intake from FAST, I already have the car water pump and accesories from a car engine to clear that intake. And flat pistons.

Which heads would be the best? Not aftermarket. Should I get them from a LS1, LS2, LS6 or LQ9 engine? Or what cast number should I look for??

Thanks in advance.

ls6 would flow like the 317 heads and would raise your compression.

Do you know the ls6 heads cast number?? Or a thread that has that info? The search button was not too helpfull....

get 243s or 799s.
