H22a Head

[Drifting in 808]

My h22a head warped/cracked and i need a new one. this is the first time im ever going to pull a head off so is there anything to look for. also where do you suggest i get buy a head from? i was thinking junkyard but it still might be cracked/warped. i dont know of anywhere that is trusted and doesnt want a rediculous price.

Well, did it warp or crack or both? If its just warped, a machine shop should be able to shave it to be flat for anywhere from $40-100.

If cracked, id look for a new one. Preferably an h22a4 head, id prefer that since it has the spring type lma's instead of the hydraulics which are prone to failing. Drop your cams in and you're good to go.

As far as head casting goes, id venture to say they are identical, but I don't have any first hand knowledge on that.

Be sure to get a manual and follow the bolt loosening pattern very closely. Improper removal and installation of head bolts are a major cause of warping on these heads.

is the a4 better then the 93 jdm h22a head? i had a friend wanting to sell one from a blown h22, but he doesnt know much about it and he wanted 100 bucks. but i think from a blown motor the head would be damaged...

I would check Craigslist. I have seen them for $250 bucks, 200 on a good day.
I had to change a head on my old cd5 because it was overheated (not by me). It was not very hard. You have to follow the torque specs and tighten the head down in a specific order in stages. you will be fine.I put a f22a head on

The head could be warped, or a piston may have made contact... but you'd have to inspect it to find out.

The F22A head (they are all the same) has the ability to outflow the H22A head. However, the best head is the one that matches the block you have. If you have an H22A block, you want an H22A head.

Just by the fact that the h22a4 heads have spring type lmas, make sure you use the cams from the jdm motor. How was the motor 'blown'?

[Drifting in 808]

i dont know how the motor was blown, he just told me he was rebuilding a h22a4 for his senior project but decided he was gonna rebuilt his b18c instead. all i knew about it was that the motor it was off of was blown.

Take a look at it, if its been smacked by a piston, you'll know. If it looks ok, get it shaved, replace the valve guide seals and maybe grind the valves while your in there.

Get the headcheck first at a local shop then if its repairable send it to a machine shop get it cut n cleaned up cometic 2 layer headgasket and arp head studs n call it a day! Lol

old post, i finnaly got the time to pull the head, i got it off right now and going to napa tomorrow to buy parts. i was gonna buy a head gasket set, water pump/timing belt. is there anything else im missing? the cam seals didnt look too bad and the head bolts looked like they were in good shape.

[deevergote]

Cam seals would be smart to replace, since if they fail, they will cause massive leaking... and destroy your timing belt.
Head bolts should not be reused, regardless of how they look. They are designed to stretch. Get new ones, or invest in some ARP studs.

also 1 more thing, do i have to put the bracket from the IM to the block back on? i hate that thing and if i can get away without using it i will.

[Krowned King]

i would, it sucks to have intake leaks and makes for a bunch of hard to track problems.
