Today I spent the ENTIRE day working on the heads. It’s the first time I put the shims in and got everything adjusted right. A few shims I had to surface grind as those were the ones I didn’t have on hand. 2 buckets had to be slightly surface ground also, so the shim was above the bucket. I couldn’t imagine doing it without the tool that allows for removal of the shims without taking off the camshafts. It was hard enough having the tool and getting all the right shims in place.
