i wanna go with a MS4 cam for the summer, not sure on the heads, i was leaning towards the ported ls6 heads, or some ported ls1 heads. i dont wanna go with an aftermarket head, any advise on which out of the two heads will make more power for my MS4 cam.

 

Call TSP, im sure they will set you up with a nice set of there stock casting CNC heads.

 

ported ls6 243's or 799's will outflow any ported ls1 head any day.

 

with the ls6 heads will i have to worry about any V/P clearance, fly cut pistons

 

As long as you leave the valve size stock and leave the deck stock you will not have to flycut with the MS4. Our stg 1.0 LS6s would be the heads I would recommend you take a look at if you don't want to flycut the pistons.

 

ok thanks, what about intake set will a ported ls6 intake be a good intake to run. what about pushrod length i think 7.4 was it, i was reading up on it and some say the 7.4 damage the lifters, if so what size push rods do i run. sorry if asking stupid question my first ls1 thanks.

 

dont waste your time porting an ls6 intake there are no gains. step up to a fast and youll see a huge gain with heads and that cam.

 

thank us guys been alot of help for my first time on here.

 

TSP will hook you up...
