91 Accord LX

Do the heads bolt up different between an A1, A4, and an A6? Cause I have an A1 and I'm not sure what type this head is off of, so does it really matter?

They should be the same...What are you trying to do?

As for as I know, the only differences between the A1, A4, and the A6 are the intake manifolds, exhaust manifolds, and the A6 has a slightly different cam...or something. And there also might be some, minor, ECU or whatever...stuff...differences.

I own a '91 EX 4 door, with the F22A1, and my dad owns a '91 EX-R wagon, with the F22A6. I've replaced the valve cover gasket on both of them quite recently, and I'll be damned if there's any difference between them.

But that's just my opinion; get a second, and third, and fourth before you start swapping heads...

F22a engines will usually swap out parts easily. I havent ran into any probs yet. About to do a H23 head swap (double cam) and its suposed to bolt right on to our F22a. Is the head on your engine fck'd?

Im not for certain so you should get other opinons, but i thought i heard/read, maybe even saw a pic, that the a1 and a4 headers are 4-1??? I know the a6's are 4-2-1 but i just remember something about the headers being different...

Yes they are different but interchangeablity is possible. EX had the Dual runners and 4-2-1 Exhaust manifolds. And as mentioned they also had a slightly more aggressive cam as cats on ice mentioned. But they are swappable. Plus the EX has a slightly more aggressive map if i remember but i could be wrong.

well I got the car for free, and idk wether the head or head gasket is bad, but I found a rebuilt head on ebay for $150, so I figure while I'm replacing the head gasket, I'll put a different head on there to, cause I don't have a clue on how much it costs to get these things x-rayed or whatever you need to do to make sure the heads are still good.

[pyro_maniac69]

also, is it possible to just take the head off WITH the intake sill bolted on? Cause I don't really feel like trying to fuck around to get the lower bolts, cause I already know those will be a bitch

yea you can just gonna need some finessing to move around.

[pyro_maniac69]

awsomeness

Like how much finess?

[NAiL05]

Not much. Just make sure you got a buddy to help you out so you dont strain your back.

[pyro_maniac69]

I might need 3 people then, 2 to pry on the head as evenly as possbile, and one to watch the intake. all well, I don't have the money yet for a head gasket set...Maybe I'll ebay it and save $40.,......hmmmmmm

[NAiL05]

Two people is good enough. You can have 3 its up to you after all.

[pyro_maniac69]

eh well, this is my first head swap on any car in my life, my only fear is screwing up the timing
