2.5 heads on 1.8?

Used to post on here until my cam broke. Got a guy wanting to sell me heads off a PGT. Would the heads fit perfect without modification? Timing these with the 1.8 crank isnt going to cause a problem? Running my 1.8 ecu going to be a problem? And im pretty sure that the trannys mount up...been a while since i messed with the mx3.....

So what about just using the cams? Plausable? I think i read here that it was possible and the only difference in the cams was the exhaust duration was longer than the 1.8 but the intake was the same.....correct me if im wrong.

One more question, 1.8 tranny will fit the 2.5 right?

All K series cams are swapable, excluding the KJ Miller cycle ones.

K8 tranny is the exact same tranny in the ford probe GT.
