Ok, well techinally not k24/k20 but rather k24/k24.

I have a K24A8 longblock from the 06+ Accords and found out that the k20 head won't fit unless different pistons are used because of piston to valve clearance. Well I was wondering if anyone knew if the head off a TSX (K24A2) will fit with no clearance issues. I don't know what the pistons look like between the a8 and a2, but I do know that the a2 is 10.5:1 and the a8 is 9.5:1. Thanks!
