Hey guys, question for ya..

Are the head and valvetrain from an evo and a twin cam the same? visiblly speaking...

If i was to up-load a photo of the rockers(and whatever else...im no mechanic!) underneath the rocker cover/box would someone be able to identify the motor it originally belonged to?

Asking as i've just bought a 89 ST, which is obviously an evo, but it has TC rockerbox's. Trying to figure out if its just got the "TC style rockerbox to suit Evo", or if infact someone has done the fatvo/fatevo/fatso conversion on it. Any other ways without pulling it down to get a better idea?

Thanks,steve.

 

Twin cam rockers/heads look different from above. They have a wiggly oil path on one side that is obvious.

Ok thanks ill have a look!
