Honda 350x head swap question. 86' trx350

[Jason125m]

I've searched and searched and have found nothing. Either there isn't anything posted about this, or I am a handy tard.

But, i'm wondering if the heads are the same between 85/86 350x, and 86 trx350. I know they swap, and i know their cylinders swap. I'm just wondering if there is any difference. IE; Different sized valves, different cam, different dome? Service honda shows different part numbers, but I read online that it is just because of the difference in colour.

I have an opportunity to pickup a trx350 dirt cheap.... Any input would be greatly appreciated.

isnt the trx350 at 2 valve head? and the 350x is a 4 valve?

Trx 350 is a 4 valve also

Pretty sure it a direct fit,the aftermaket top end gasket kit is the same part number....trx350 cam better for low end torque,atc more rpm
