ok, you guys know way more than i about these engines. i'v only built 3 and this will be #4. thanks for all your input here. originaly i thought maybe instead of totally blocking left galley i would drill a .060" hole in the plug just to get enough oil when street driving,which wont be much street driving. i have restricted oil to the rocker shaft to .060" each side since a spraybar oil rockers. my cam also full time oils. so looks like i will be fine blocking left oil galley which i will do. thanks again
