Has anyone determined the "limits' of milling a 289 head? Need to make up for some combustion chamber work to get the comp. ratio back to 8.75:1 and believe that 0.060" mill is about right. Anyone cut through the face at this amount? Has anyone cut through any amount? Realize that there is a difference in casting thickness, but would be nice to know of limits before starting.
Thanks a lot, Paul Keller
