Yes that valve size is used often w/that bore size. But....what head are we talking about. This is the more important variable to speek of here. Are they spread port heads? If conventional heads, i'm gonna say thats way to big. Unless your using a one-off casting w/moved valve centers.
Most always with that bore size, i personally use 2.300". On something higher effort, maybe a 2.325" at most.

Well right now ur already doing a set for me as we speak, but I have bought another new set from the west coast(killer deal) u also done with new ti valves (2.400 ) and ex.

The problem is I already ordered pistons (quick16's) for a 4.500 bore. So I was just thinking about using the other heads first with the ti valves if it would work. Could always get more pistons later!
