Exclamation Porting intake base, plenum, heads

Hey, what bits do I need to port my aluminum base and plenum and my cast iron heads? I need a shopping list. Thanks.

You will probabbly need:

a dremel tool w/ the bits
-drum sanding roll
-tapered metal cutting bit
-drum metal cutting bit
-tapered sanding roll

I think that should work

No, a dremel won't work well.

You need an electric die grinder with a 1/4" collet.

Go to the link at the bottom of my sig. It has lots of info and pics showing just what to do with the heads.

grinder....

I have an air operated die grinder. Are the kits from Summit or similar worth the $40.00?

No.

As I said, go to my thread and read it. It shows you everything you need and how to do it, (except for the plenum but that is just port matching and hogging out anyway).

What more could you want?
