difference between heads: 121 121T 118?

[jetboy]

So i went and picked up this head, just because it was cheap and i thought i could clean it up and have a nice replacement ready in case- Buddha forbid-

it was advertised as a 121 head, and I didnt even notice until i got home that it is clearly stamped 118. Then I took a closer look at the head on the car - and noticed that it is stamped 121T -

So what is the difference between the 118, the 121, and a 121T ?

thanks!

121,121T, and 121Ti are all the same head, same combustion chambers and same valves, same cam. This is the first generation 2002 head. It has small combustion chambers and good for high compression.

The 118 head is the 1600cc head. It has smaller valves compared to the 121 head. It uses the same cam though. You can only use this head on the 1600, 1602,1600Ti,1800,1800ti,and 1802 engines. This head also has smaller intake and exhaust ports compared to the 2 liter heads. It can not be used on the 2 liter motors. Let me know if you want to get rid of it.

well the 118 isn't doing me any good unless I buy a different car- so yeah, I am open to offers- i paid 30 bucks and drove 100 miles to get it.

it comes with the cam, looks clean enough- no burned oil or anything- but no guarentees on cracks. I was going to get it tested but dont really want to shell out the 40 bucks for that now! heh.

if no one wants it i guess I could keep the cam, if that 's exchangable - i should check, maybe its some sort of performance cam.

thanks--
