Got a little work done today on the engine. Getting really close now. I bought the Hughes thick walled rocker shafts, but they have small holes in them. My heads have 3/8 bolts and wont fin in the new shafts, Is it gonna be ok to just drill them out for the heavier rocker shaft bolts. I have one head torqued on, all the lifters in, and am now waiting on the rocker bolt issue.
