I'm thinking about having my intake Extrude honed, I'd like to here if anyone has flow numbers from doing it and are they satisfied with results, or should I have it Hand ported and polished? The cost of extrude hone is $833.00 so,it isn't cheap. I haven't got a price quote on hand porting yet but assume it is about the same.:scratchhead:

Seems pricey??

I run my old mopar in F.A.S.T and a lot of guys have moved from extruding exhaust manifolds to having them coated (similar to outside of manifold) as it increase flow at a fraction of the cost. I know it is not intake side as you asked, but thought i'd add these tid bits for your consideration.

The issue is how much air are you trying to move ?

Are you a stock 6.1 ? a 426/440 car ?

If you are stock displacement and port match clean up will do you just fine.

If you are going to go max effort big stroker and want to use the 6.1 intake then you will need to have a full port done and extrude home to get where the porter cant ( without cutting and welding )

It really is about being cost effective and what your end goal is.

If you are staying with a 6.1 size, I would just have the intake matched to your heads and do a little smoothing and clean up work in the intake.

No need to go nuts, unless you are putting together a max effort set up.
