....and I totally agree with both of you, and Ol' Ron.
I had a '35, 21 stud block built in 2002 by an engine rebuilder in Southeastern Pa. Basically he did all the necessary machine work, and I put everything together. He recommended using HiTac sealer on all gaskets, so that's what I did. What a huge mistake that was when I had to tear that engine apart after only 2000 miles for an internal problem that needed to be corrected. Every single gasket was totally bonded to it's mating surfaces, and it took me untold hours to get all of that crap off every component that was bolted to the block.
After posting about the mess I had here on the Barn, several members who really knew what they were doing when assembling these Flatheads, suggested I just use grease on all gaskets and their mating surfaces, and that's exactly what I've been doing for the last 16 years. Never had to spend time again, removing old gasket material stuck to any components that required gaskets for sealing.
