Default ptv clearance on a milled 243 head.

Hey all,
I have an 05 gto with a 234/236 .600/.600 112lsa cam. I am going to get a set of tea 2.5 243 heads. Would you guys recommend milling these at all for some more power/compression? I don't want to worry about the valve hitting the pistons though.

Yes the ones I am looking at now are patriot 64cc heads. I understand that patriot doesn't mill the head to add compression. But I might be able to get a set of patriot stage 3 64cc heads on here. I need to make sure they will work first!

With the bigger valves I think you will have to run gm mls to stay in the safe range and only a small mill (.010)....112LSA straight up or advanced any...I think you will have to measure especially if advanced.....
