Default PTV problems with T-Rex and Stage 1 PRC's?

Hey, I'm running a T-Rex v.1 and are probably going to go with a set of stage 1 PRC 243 castings from TSP. This is on a stock bottom end (with rod bolts, of course.) Think I'll need to flycut? I'm definately going to check when I get whatever heads I decide to go with, just wondering what you guys think?

You will not need to flycut! We have extra p/v built into those heads for the larger camshafts!

Not exactly sure on the CR, but I assume around 10.5ish. Haven't decided whether or not I can safely mill the heads.

They have the ability to sink the valves....

On my 2.5 LS6's I had the valves sunk .040 to clear my G5X3...It ran like a top!

Nope, still waiting on ordering them. We'll see when everything gets here! (Waiting on a few misc parts, suspension, heads, etc.)
