Extrude honed heads....

[O SO LO]

I see alot of guys have ported their heads, intake and exhaust..
I was wondering if anyone has ever Extrude Honed theirs?

Check out their automotive section at extrudehone.com

theres no need on the heads but i was thinking about doing this to an intake but never did.

I thought the main purpose of extrude honing was to hone out things you couldn't do by hand, like long intake runners. I think since we can reach everything it probably isn't that practical.

Ive had some stuff Extrude Honed.. it worked well on the parts I did.. I dont think it would be worth it on heads.. on a hot air intake tho, it might be worthwhile. I'd probably port it before I sent it in tho.

Prolly would work well on all the funky twists and turns inside the hotair intake.

Isn't it pretty expensive?

Sorry, I was thinking of an 86-87 intake.

not sure on the price i havent found anyone that does it but then again i havent looked to hard.

Extrude Hone does it. They have an office in PA and I think one in CA. It is pretty expensive.

i wonder how much this helps? anyone have pictures of before and after shoots of this done. i have done alot of reading on this but havent heard of any gains or real feedback.

My heads are extrude honed. I'm pretty happy with them but it is expensive & if I did it over I would just have bought aluminum heads. I could have for what I have in these. I had an intake (which I didn't use) and my heads done at the same time back in 2000. Cost then was $1200.

wow, thats expenise. why would you extrude hone the heads? cant you get to all the areas by hand?

The only problem is that process takes material from all sides of runners.Removing material from floor of port is lowering the runner Other than smoothing out inperfections in the casting the floor of the runner should left alone.I guess with a turbo engine it would not matter as much. I have seen n/a engines that had runners raised so much they had to weld the top of the head and cut and weld the intake to match .then epoxy the floor . A good cnc port and some smoothing is probably the best .just my 2 cents
