The finish that most machine shops put on the block and head is too rough for use with an MLS gasket because their equipment can't provide the finer surface finish that is required. So don't assume that because a shop can resurface your head and block that it will be ok. If they have to ask you what surface finish means, then they probably can't perform the task correctly.LOL
Well I was planning to just a head through Tom and have him do all the work. So I assume his heads will be MLS gasket friendly. But I was wondering about my factory deck finish on the block? Like I said, I'm postponing a bottom end rebuild for later on down the line. Focusing on swapping out the integrated top end and doing a cam swap.
