ptv clearence gurus step inside
ptv clearence gurus step inside ls1tech is so full of different info on exact specs on this stuff and different formulas on how to find it i cant tell which ones are correct. so maybe someone that has done this before will chime in. the car is a stock ls1 bottom end. cam is .605/.610. duration is 238/242. the heads im looking to get are 5.3 heads with 2.02/1.60 valves and have been milled .030. will these heads cause ptv clearance issues? the gasket is planned to be .040. if they will work but not with that gasket what gasket is recomended? thanks in advance for the help.
no way it will fit that is close to the size of a ms3 cam, and texas speed has to recess the valves in the unmilled 5.3 heads just for it to fit with a stock .054 gasket...so you are .030 plus .014 gasket... plus i am guessing unrecessed valves...so you need to flycut some or get pistons...
