I have done everything with this block, this was the third time it has wipped out cam bearings.
This last time I installed Durabond coated bearings and then measured each cam journal bearing and then the cam. I then cut each cam jounal to give it 0.003" clearance. It turned real nice and I thought I had it finally fixed, NOPE!!!
When you say it wiped out the bearings, just some clarifying questions: 1) what does the failure look like ?
Camshaft Bearing Diagnosis 2) is it on all journals or is it a repeated failure on just one?
