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!

Awesome, that answers my question! Now to just wait on parts, etc. to get here so I can put it all together, hah

extra p/v? can you clarify this please?

also, what would the CR be on this combo?

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!

hmmm........that's very interesting. i've never heard or thought of that being possible. thanks alot man.

btw....if you're running stock pistons, have you ever had your CR checked with those heads? thanks.

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

what about the Terminator heads are the valves sunk as well?

Sunk valves = potential shrouding??????????????????????????????
