I know the valve springs are alot tougher on the A6

you wouldnt never be able to tell with out testing the springs.. im pretty sure he means by looking at it..

[CB7Man]

I can tell by pushing springs lol
Go to a JY often and play around with things.

so the heads do not have any numbers or anything on them?

when i bought my new head i asked for a F22a6 head and every place i talked to said the are the exact same thing you would find on a f22a4 or a1 . so i thought i would call up the Honda dealership and talked to the parts guy he said they are the exact same thing. anyone here anything different?

[joshjones84]

I think someone should wip out there micrometer and measure the lobes. then everyone could stop guessing if they are different or not.

[CB7 Sleeper]

measure lobes with a micrometer as stated above. that sounds logical.

i heard from alot of people that the a6 cam is bigger not by much but its bigger

My Chilton says that the camshaft specs on the F22a6 are in. 1.5252 and ex. 1.5343 and the a1,a4 are in. 1.5167,ex. 1.5266. So lobes are a bit diff. on the a6 but not much! But I think if you ask if the head is the same it prob. is but the cam is diff and maybe the springs too?

There was a thread about the markings on the dizzy end of the cams for A6 vs. A1/A4, I posted up the A6 marking, not sure if someone posted the A1/A4, but the end of my old A6 cam is marked "4B". See what that cam is marked and try to find out what A1/A4 would be aswell. All F22A heads should be PT3 castings, no such thing as a PT6 head, the castings are all the same minus the A6 valve springs and cam.

I also must agree w/ Deev from your 2nd thread, A6 cam is an upgrade, but not by much, Bisi stg 1 or even 2 would be way better.

To add to the knowledge here, I have an a1/a4 cam sitting next to me with "3A" stamped on it the dizzy end.
