Good morning all! I've chosen a machine shop to do the work in my Y and in my "poking" around I came across the mod to get full oil pressure at the rockers and the .060" hole in front behind the cam plate for the timing chain. I was planning on dropping off the block, crank, etc to the shop on Monday, but before I do, I'm looking for opinions on these mods....worth it? Necessary? Also, with the hole drilled behind the cam plate is it necessary to fab up the little sheet metal thingy? Thank you all for your thoughts and time!
