Re: Checking Head Surface for Flat?
Just relaying my experience... after decking many blocks/heads/manifolds... I use a long machinist strait edge... which was why they were manufactured/made/used... back in the day and now. I check front to back and diagonally and use a .0025 feeler gauge. Once machined flat mine always pass the test. I haven't had any issues and don't have any computerized equipment to check otherwise... neither did they 40 + years ago. I think we can beat this stuff to death.
I say use a good machinist straight edge, use it right, check it right, and take necessary steps to get the head/manifold/block straight as required. It's not brain surgery and good thing...
