Default Milling STOCK HEADS

Would there be any benefit to milling stock 5.7 heads on my '01? By stock I mean no porting or valve changes I am going with a 224/224 .560 .560 on 112 anyway. I don't have the cash for a set of ported heads yet also how good are the Patriot Performance stage 3 5.3 heads. I'm serious about wanting some compression. Also any other words of wisdom are very much appreciated.
Thanks

Piston to valve will be your main issue with that cam. If you don't have access to proper cam degreee or valve/piston checking equipment, decide on the safe play and only mill the heads enough to ensure proper head gasket sealing. Larger valves can lead to less valve/piston clearance. Can't comment on Patriot's heads since we haven't seen them yet.

Good luck,
Richard

Mine were milled 60 thous with not problems and the C2 224/224 581/581 112 XE/R cam.

You should be fine. I would go with 918's a minimum for that size a cam.
