Question, is there any difference between the h22a1 and the H22a JDM head? I know the bore and stroke are the same, compression is higher on the block. I can get a JDM head for a decent price and I'm curious if i should grab it. are the ports bigger? Different cam profile? Blah blah blah?

 

Guys, I hate to bump but I'm throwing my H22 in the accord sometime next week. We already have the F22 pulled.

 

I'm sure there are some minor differences, but its not worth spending the money on one and taking the time to install it. There would be very little to no horsepower gain.

 

Thanks. I figured as much but it never hurts to check.
