Specs for machining 243's Ok guys need a hand here. I have come across a set of 243's that a buddy was pretty much going to scrap because he is upgrading to a set of AFR heads. My question is he picked these up used and they were supposedly milled once? Who knows!!! Is there a point on these heads where i can mic to see if they truly have been milled. I have searched around on here but can't seem to come up with a good answer. When we take our heads to a machine shop i'm sure they have all these specs somewhere right?? And i will need those specs as well. Thanks

specs Thanks for reply guys...Anyone know how many cc's a stock 243 head is? Is there a reference for cc size to cr with stock pistons. At what point do i need to be concerned with flycutting? What is the minimal limit of pvc? I plan on claying the engine once i get a new cam. Thanks again for the info.
