i would recommend doin everything stock but it sounds like you want some horsepower gains so upgrade;and at least replace all the top end with new parts oem or aftermarket!

Alright here's the deal the camshaft is not an f22a4 because the a4 cam shaft has the following markings (3A,E,RC,G) the camshaft that I installed has the following markings(3A,D,RC,M) the "M" is also painted red.
Like Deev said, it is modified, the cams are smaller in width but they are the same height.
Thus giving a lower closing position, and raising the lift. Am I right?

I can't envision what you're describing, so I can't say for certain.

That red-painted M is apparently something found on stock camshafts, so it may not be an indictiation of aftermarket as I suspected.

The F22A1 and F22A4 have identical camshafts. The F22A6 is different.
We really should make a thread that shows how to identify all of them.

The f22a1/4 cams have 3A on the end.

The f22a6 cams have 4B on the end.

alright that makes sence because the camshafts both have the stamping 3A on them and the same lobe lift, but the one i bought off of the guy with the gear, has a smaller base circle or lobe width.

Hey Deev, i was at work and it was slow, i got out the oxy torch and i freed my cat from my downpipe. (previously seized together) so now this friday when I do the head swap, I can also put the cat back in, I don't want to be disrespected because of a cat delete, plus i have to get emmissions done in a month so i just saved myself $200

are you trying to keep it stock, if so go with an f22a1,a4, or a6, if you want to mod it you can use an h22 head

Putting any head other than the F22A head on the F22A block is a waste of money and effort, and will result in an unreliable engine.

If you want an H22, buy an H22.

so I replaced my head last weekend and my car isnt running im pretty sure i messed up my timing. But anyways, i wanted to bring this up to everyone's attention. My cylinder was smooth, no gashes, and has the factory hashmarks. The engine also has 260k that is some amazing engineering and tight tolerances
