I have a banger up cylinder head from multiple rebuilds. Due to the thin areas to clean it’s hard to keep it straight when working with the razor or the glass. And I have a cam holder that’s perfect. I have a NOS gasket. I’m last build I had the gasket creep out leading to a leak. Wondering if I should should a sealer. I have assembly oil, hondabond, grease, and copper spray on hand. I have read about gaskacinch on here. I’m putting it together tomorrow.
