I broke down an ordered the Tomahawk windage tray after reading it's made of thicker metal. I needed a new oil filter adapter from Butler anyway. Still waiting on the heads. He promised me he'd start at the end of the week, but he's been saying that for about 3 months now.
In the mean time, I've been trying my hand at gasket matching and modifying the repro RAIV intake. Been using a cordless multispeed Dewalt grinder I picked up for this job some aluminum grinding bits and a kit of sandpaper rolls from Amazon. I've been running the grinder at the lowest speed (10k), seems to do ok. Right now I have the ports rough finished with the 80 grit rolls. I've heard you want to leave some texture on them, not sure how much is ok.
In addition to matching the ports, I opened up the carb plenum. I used pics of modified intakes I found in the forum as a guide. I didn't do the notch between the secondaries. Seems the benefit is debatable?
At this point, I think I'm only limited by my knowledge and skills

Hopefully I'm not doing more harm than good.
