Well in the future i plan on doing a full H/C swap, ive done research and love the MS4 cam. My setup would be TSP LS6 CNC ported heads, MS4 Cam, PR gold Dual springs, hardened pushrods, comp R roller lifters, Rollmaster Double roller timing chain, along with getting my LS6 oil pump ported. What do you think this setup would give me with my PS headers, 3" cutout, all free mods, and a LS6 intake????? im hoping around the 450 range possibly.

 

You need dual springs with that high of a lift cam.

 

ok ill change that

 

Factor in flycutting and bumping up the compression. Do some research on DCR and what static compression you will need for this cam to work at it's best. Also, I recommend the competition valvejob if that wasn't on your list.

 

Do i really need to do the flycutting with the MS4 cam??? which heads do you think would be better with the MS4 cam??

 

No you do not need to flycut for that cam to fit with those heads. However, to get the most out of that setup you need to bump up the compression by milling the heads. When you mill the heads you will lose some PV clearance and need to flycut.

 

So basically i cant use those heads to get the gains i want, what heads would go well with it?? PRC stage 1.5 heads?? or PRC stage 2.5 heads???
