Would using a 2.2 head from an 05' make any difference in an 03'? Thxs

The bare metal head is identical. The only differences are camshafts and springs.

Ok cool! Thats what i thought. Reason i ask is. Im having a turbo installed. I thought it was a good idea to go with the 2.2 head for the beefed up valve springs....What difference would the cams make if any...?? thxs for your reply!

ummm....Honda lowered the redline on the 2.2 for a reason...........revving to 9K with a 2.2 head could be asking for huge $$$$ problems.

Im not sure that will matter...?? Im going to use a 3mm head gasket and the 2.2 head has bigger valve springs and retainers then the 03'. The only question i still have are the cams...?? Anyone...?? thxs

You missed the point. The 2.2 head has valve springs that are weaker than the 2.0. This effectively limits the redline with that head. If you rev that head to 9000 rpms you might need a new engine because the valves will float much sooner than the 2.0.
Installing stronger springs and light weight titanium retainers will eliminate the problem.

I read what i wrote. It didnt come across right. The 2.2 head i got did come with beefed up valve springs and retainers already...I didnt mean to imply the 2.2 stock springs were beefed up. Thats why the only real question i had was the cams.......Sorry for the confusion!

Not to create controversy, but I assume you have factual data to back that statement up.

Many on this board have been shifting F22 to 9k reliably for over a year know.
