Machinist will not build engine unless roller cam is used!

Nope, no ticking. Sometimes, the ticking noise with retrofit hydro rollers comes from worn lifter bores in older engines. I had my lifter bores bushed, so the whole shebang is new and working together. The bushings had .040 oil holes drilled in them before install, and that concerned me after seeing the size of the original oil holes. Machinist finally got me convinced it will be ok....lol.
