I was wondering what everyone took as acceptable grit finish on the intake ports, 80 or 100, smoother or rougher. It will be on a high boost 355, so I didnt know if it differed between n.a. and forced induction car. Also I was reading a box from Joe Mondello and he said that the rocker stud holes should be epoxyed smooth to cut down on and turbulance down the intake runner. If so, what type of epoxy are you using or recommend to be able to use in the holes that will hold up to the heating and cooling of the aluminum? Thanks for you advice,

 

According to an article I read, Mondello recommends 50-60 grit for intake ports and 300-400 for exhaust. I don't think it'd matter whether the air was coming from a supercharger or n/a.

As for epoxy, alot of guys like to use A&B. I've used it before and it's pretty durable. If you're gonna do that, then you need to make sure the surface to be bonded is rough.... kinda like the fuel shredders on the plenum-floor of an intake manifold (those that have them).
Me personally, I wouldn't use epoxy in an engine I wanted to keep together for more than a year. The stuff is notorious for falling out when you least expect it.
