Just was curious to see what all cylinder heads people are running with the MS4 cam and what power they got with their combo. Please say if you had to fly cut or not.

 

i wanna know as well

 

no one?

 

Talk to TSP, they will be glad to help you out.

 

Ported LS6's would work....I dont have them but i know they will fit.

 

I would be flycutting no matter what with that cam.

 

i was curious as to if anyone was using like etp or tea or some other aftermarket heads besides prc. i've read everything there is on the prc's just about and wanted to know if anyone has tried any other aftermarket head with that cam

 

I was told with the MS4 you are very limited to head options. Pretty much have to stick with stock valve size. They said their LS6 stage 1 heads would work but I can't remember if their 5.3 stage 1's have the same valve size? You go up on their stages and the valves get a little bigger. They recomended staying with the LS6 heads.

 

Im running the PRC Stg1 heads with MS4 and no flycutting. In the GTO (through an IRS) I put down 420/390.
