Yes, I got the stock valve covers to work with both my Canfield Heads, and a set of Windsor Jr. heads I had. It's not enough to remove the baffles, you have to cut the studs the rivets go into. If that won't clear, then get the Trick Flow valve covers. They are cheap, and will give you lots of clearance on the intake.
You are going to max out that Lightning MAF with a 363 engine. You are going to need a better MAF. The Lightning MAF has the cross sectional area, but the electronics aren't very good.
I am working on the starter. I thought I had the specific part number here. There is a power master equivalent available. This is what you are looking for.
This is a starter based on the Denso gear reduction starter used on so many factory vehicles. This starter can pull the car up onto a rollback. Ask me how I know.
