Reply to "Is this screen too fine of mesh? Opinions?"

Call Aviaid and ask them what they think of adding a finer screen to the pump pickup on your particular engine. Aviaid's screen is very similar to what Ford now uses on its modular motor pickups for their crank-driven gearotor pumps. My guess is, your two screens will cumulatively restrict about 75% of the flow into the pump, but it may still work OK. If you're worried about more steel bits getting into the pump, many of us use magnetic signs cut to size. I have one wrapped around the whole remote oil filter can (backed up by a tiewrap), and I've seen others magnetically held to the bottom & sides of oil pan sumps. No magnetic bits will move around with something like that in the area.

A simple rocker arm option is to save your money and buy a set of stainless steel rocker arms & sell what you have. The aluminum ones can be made of 3 different alloys: 2024, 6061 or chinese-mystery aluminum. I doubt Roger used cheap assemblies- that's not his style. Aluminum assemblies work fine for normal street valve spring pressures. Mine (bought used from a roadracer) have been in my engine trouble-free since 1992 and they are NOT top-of-the-line. Stud mounted rockers WILL NOT WORK with your SVO/Yates heads- they were designed for Jesel roller rockers and lack the production stud bosses.
