I bought the MS3 cam the other day and I was wondering if I'm going HAVE to flycut. I know that the PTV is going to be the bare minimal, but I plan on doing heads in the future and would like to hold off on the flycutting until then. The valves, gaskets, and the heads are all stock (no milling). Thanx in advance.

 

MS3 is fine with stock heads.

 

i honestly don't think you need to flycut, especially since you have OEM heads w/out milling.
is this an LS1? sorry for the dumb question. if so, i believe the cc are 66cc on those heads, 241. but, always check to at least know where you are at.

 

well what heads are on the car and what lsa are you running?

 

it clears.

 

They are the stock 241 castings and the cam is on a 112 lsa
