I was wondering if someone would let me know if PTV would be a problem on a stock 346 with 241's with a 236/249 .647/614 112+4....hopefully someone will let me know...also what size head gaskets (thickness) would you recomend?

That's gonna be really close on a stock cc head. Absolutely check on that one. Why you running such a wide duration between the intake and exhaust? You plan on spraying the hell out of it?
I'd stick with the thickest gasket you can if you want to keep from flycutting.

there is no such thing as a definate answer when it comes to PTV. every engine is different, and the only way to be abslotely sure is to check it yourself. if your dumping all this money into this motor and you skimp out on things like this for advice from someone on here who may not have a clue, your just asking for problems. do it once, do it right.

Well then, why don't you play it safe and go ahead and flycut. And since you're basically running a custom cam there's no definite answer that it will even clear the PTV. Even the shops on large cam's recommend you check the PTV clearance. Call up TR and ask the PTV clearance on the T-Rex. Yes it's made to clear stock heads, but they still advise you to check first. Like said above, every engine is different.

You'll need to check, it will be tight. It certainly will not have .080/.100 clearances ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
And if this is a stock block, how big do you think you can spray before it grenades itself?
