I have forged pistons w/ valve reliefs...do I really need to check PTV clearance?

Just as the subject says. I will if I need to but really is there a reason for it?
Cam is 229/234 .610/.600 111+4.
Heads are trick flow as cast 220 milled to 60cc chambers.

yes. more than likely you will be ok, but common sense says to just check to be absolutely sure your specific combo checks out.
I have a less aggressive cam than you, less head milling, and Wiseco's with valve reliefs - I'm about 0.250" PTV. Here is my writeup:

Dude you asked. Everyone told you yes do it. You are arguing with everyone who said to do it. You clearly don't want to. So put your engine together and roll with it. I mean who cares about knowing and being safe when you just want to be a little lazy and not safe.

i have stock LS3 heads milled only slightly and wiesco pistons with 3cc valve relieves and an EPS 236/242 .629"/.629" and i checked just to be on the safe side. Wouldn't you rather check it now, and know its right, then to go to turn the motor over and think it's right?
