ej20t heads on ej22t block ?

[twinturbowrx]

ive been searching on the internet for a while and i cant really find any how to or info on taking a set of wrx heads 2.0 that i have and putting them on my tleg block. i know that you can do it with a set of 2.5 heads but i want to know if anyone knows if they will work and will i have to worry about the length of the rods and pistons and all that other good stuff and what would the cr be?

Oh, it's possible.
I can't possibly go into detail or take credit for what this member has done for research in comparing all the differences between the different DOHC heads which will work with the "t": http://bbs.legacycentral.org/viewtopic.php?t=38247

sooo i checked out the site that was posted maybe i missed it somewhere in there but im just worried about the piston coming up to far and cracking the head or something else bad ha

^ The difference between the 2.0L heads and the 2.5L heads as far as piston clearance goes is not drastic enough to cause that problem.
