Trickflow 235's on 404" LS2 - PTV clearance? Just got some trickflow 235 6 bolt heads bolted onto my 404. Installed one set of rocker arms, and pushrods. Went to turn the motor over slowly. It stopped half way through the cycle. Took rocker arms off, turned motor over with no problem. Using a 7.450 PR. Haven't got a PR checker yet. Wasn't going to run without checking, just wanted to see how close I was going to be. Could the wron size PR make the valves hit the pistons? Here's some specs on everything.
-2cc diamond pistons
.010 piston out of the cylinder( I BELIEVE )
254/257 .612/.612 @ 110+3 custom Pat G cam
Stock GM MLS head gaskets (.054 compressed I think?)
I ran this motor before with patriot stage 3 317 heads, with the same cam, and didn't have any problems. Actually made 500whp with the same exact combo. I'm leaving for work so I haven't messed with it anymore. But was just trying to get some ideas to try tomorrow. Thanks guys.

Did some more experimenting with it today. Don't think I'm hitting the valves. It was just getting to where the cam was opening the valves. Lol. Told you I was in a hurry. Only took maybe a 1/8th of turn to get to torque from zero lash on the exhaust valve. And maybe a half turn to torque on the intake. Definitely need new pushrods. Got to get a pushrod checker.
