Headwork done to your F22A?

[LX Rida]

I was just wondering if any on here had any headwork done to there f22a head and who did it and how are the results and if you think it was worth it. Thanks

[WiKKeDV16]

the head got shaved on my sisters accord if that counts??

45 thousanths..

hehe..


pros:
faster accleration
second gear feels like first accel wise
alot more torque

Cons:if its done wrong you could leak oil
running lean due to such a high compression ratio


i installed a dc sports header about 1 week ago or a lil more
and was getting a fuel supply Cel
installed a 0-1.0v a/f gauge and its reading lean the entire time
so im thinking the ecu is thinking that there is a problem with fuel delivery when there isnt.. the car runs flawless..
so i got to find a way to richen it up..
but the power increase with the header on really let use of that milled head..


bleh im done ranting

How much did it cost to get it milled? and did you put it back on yourself?

[WiKKeDV16]

dont remember.. i believe zigeballz said not to get charged more than 200.. thats with u taking the head to them.. ill let him chim in.. i forgot what he said was avg rate..

and no.. the motor was rebuilt a lil while ago.. so .. it wsa all done together..

[alb_accord]

yeah it goes about $150 to get the head to them so they can do a whole tune up on the head. clean everything the hole 9 yard. the its $200 if u wanna do that kind of thing.

Yea that sounds like it could be dangerous...they really have to get it even and right. I wanna get mine milled to ~10.6-11.0, but on the stock ECU that's prob. not a good idea at all I'm guessing...

[ZigenBallZ]

oh hell no...


for a mill I wouldn't pay more than $80 max... I paid like 65-70...

for a good 3 angle valve job I would pay about 250-350 max...


milling is cheap and can be done in an afternoon if you are nice and completely disassemble the head for them.... unless thye are really busy like most good machine shops are and you can end up waiting a week or more...



and I've done some portwork on both F22 heads and mani's...with good results...

the thing you'll realize after seeing some pro done heads and mani's is that street work is pretty mild and mostly cleanup with a little reshaping and that's it...

the only exception is extrude honing... the manifold I saw that had been ported then extrude honed was absolutely beautiful...

So what's the end result of having the thing milled?

More HP? How much? Etc.

Yeah I wanna know too.

Haha you nervous? J/k...I took a thermo class last semester, ideally upping the CR from 8.8 to the mid to high 10s will give about 10HP on a fully stock F22Ax. But if you have all the bolt ons, a wideband O2 and an AFC honestly I don't see why it couldn't make a good 15+. While I'll probably just get my head milled I think lightweight rods and pistons would definitely yield more with the same gain in compression...but anyone's guess is as good as mine. Def. a good mod for the $$ IMO.

hmm....sounds nice...but whats the most you can mill off the head..i heard .045 is quite a bit...

The headwork on the F22a1 has been finally shipped to Michigan, I have to pick it up however. I had a guy from CHR in Colorado do the work, so I have yet to see how well it was done. I had a valve job done, new valve stem seals, port & polish, etc done.

Whenever I get the engine running, I'll let ya all know. But it won't be for a while.

Yeah sure...

It's complete right? never been messed with?

I'll trade you some portflow stiffened inner springs for it...whaddya think?

[aero]

since he posted that he had one for sale.. so do i. Its a rebuilt head for the f22a1. It was run on for 10-15 minutes, and thats it. There was a bad head gasket... leaked oil, so i just decided to put an h22. I wont have the head for sale until I make sure I have everything off of it that I can or will need for the h22, but should be for sale in 3 weeks or so. So if anyone is interested...
