Am I going to have issues :( I ordered a set of stage 2 heads (5.3L) and a cam (230/224 .575/.563 111LSA). After talking to a couple guys I know, I was told I will have piston to valve clearance issues! Is this true, because I'll try to change my order then!

Re: Am I going to have issues :( I doubt you'll have any p2v issues... still a good idea to clay it but I don't think you'll have a prob....
I'm running a 224/224 563/563 cam in my car (Stage 2 5.3L heads, no milling) and it was fine... I know others with the TR 230 cam and milled 5.7L heads and they aren't having a prbolem...

Re: Am I going to have issues :( You shouldn't have any problems, but it is ALWAYS a good idea to check. We have run similar heads will .025" milled with no issues with that cam.

Re: Am I going to have issues :( My first set of heads were 5.7's milled .030, and my cam was 228/236 .571.602, and when I clayed it, sure enough the valves hit. Set those 5.7 heads back, and recieved 5.3 heads milled only .005 for straightness, and now the car runs like a raped ape. Just to be safe, ALWAYS clay the piston first.

Re: Am I going to have issues :(
While we're on the subject of 5.3L heads, what will the compression be with a set of unmilled 5.3 heads?
