Berek, I checked, and the head I have is from a 2L as well.
I dont know how I got it, but that's what the casting numbers indicate.

it's for sale in another thread.

1592cc head and 1756cc head both have the same combustion chamber volume, so no increase in performance beyond the 1.8L head.

Hi Berek !
Is your 1800 head beyond repair?
since all these engines are from 70-80es most of them need at least an overhaul before you use them, so if you only need to replace some valves and (don't know the correct word for it) grind the seats ,replace the valve stem seals so you can get it to run again!

Its a shame that it is so expensive to send a head from this side to USA, i have at least 10 different heads that should do the job for you,
Here we use the 1585 head,(Strada,Regatta,prisma)for performance upgrade.
Its the same as 130TC, they have the 43,5mm intake valve and inner diameter of the valve seat is bigger, about 40,5mm.(1,8 and 2l to -82 have 37,5mm valve seat diameter ) but slightly smaller intake diameters than 130TC, it is perfect to enlarge a bit in the port intake roof so the port center line gets higher/bigger and straighter to the valve,great flow!

Since i don't have a clue about your emissions and smog stuff from USA,your head specs seems different to the European heads!
Here the 1,8 (42-42,2mm) have bigger valves than the 2l (41,5-41,9mm) up to about -82 then the 2l got the 43,5mm intake valve,130TC, 131(superbrava), Argenta!
So if you use a 1,8 or 2,0 shouldn't do any major difference except for perhaps the smog stuff and combustion chamber volume.

Perhaps i am wrong? since i don't know about your smog stuff, whats the difference in your 1800, 2l, 2l FI heads?

Hope you get your engine running soon !
Best regards

Hi Alf,
Ya the head is beyond fixxing sadly to say :>{ When the first valve gave way it took the second with it. THe exhaust side seat could be cleaned up but the intake was battered so badly it is beyond all hope. I thought that maybe there would be some kind of inovative thing that had come about but I was sadly mistaken. I visited two machine shops one of wich is a long trusted friend and both of them told me the same thing. I was mortified to say the least. I am a single Dad with a toddler and this was the only trans I have.Lucily for me my GF has been helping me get to work but alas that could come to a screaching halt. Oh well. So I need another head and a number three piston.
