I just got a set of aluminum L98 heads for my IROC and figured I may as well do a little bit of mild porting to them.

What I was wanting to know is what dremel bits should I use to take the material away and what ones are best to polish it to a shine?

Any other tips are appreciated.

Thanks for the help

Robert

 

i use carbide tools fro my die grinders since i have a cheap source for them. for soft metal high speed steel bits would work ok. for aluminum you'll get better chip cleaning if you keep the tool lubed with wd-40 other wise it'll load up with chips.
