Message I have a set of heads i was planning to reuse on an upcoming project. I disassembled them and checked the surface for warpage. One head is .008" warped. The service spec in the fsm is .004, the absolute limit for block and head millage is .008". My question to you is; can i mill .006" off of these heads and still be safe, and retain close to stock compression? Would i be better off just sourcing new heads?

......And just as they're about to catch me.....Twin......Turbos......Kick.......In!
