Milled Heads
I have just finished up hand porting my own heads and will be taking them to a machine shop to have a 5 angle valve job and the spring pressures setup. The machinist has recommended that while I have the heads off he could flycut them to add some more compression. I have searched high and low but can't seem to get that warm and fuzzy, for how far I could safely go. I will be running 228/228 duration, .571"/.571", 112lsa +1 cam on a set of stock 241 heads. Can anyone confirm if .025 will work? I want to stay on the conservative side.
Any help appreciated!

Richard thanks for your reply, the valves will remain stock and I will also use the stock GM head gaskets. Seeing as the opinion is coming from West Coast Cylinders, I feel confident that .030 it is the way I will go. Will there be any problems fitting the LS6 intake back on? Also do you happen to know what the compression will end up at? or possible HP gains?

I wouldn't hazard a guess as to the hp gains from compression increases alone, but overall torque should be up across the rpm range.
