i have been having a problem with a compression leak in to the radiator which blows water out. i have changed the gasket and had some areas spray welded as some of the water passage holes are very rusty. i found another head, but the combustion chamber is different then the head on the car-it covers or is the size of the gasket (will try to post picture) i don't know which head is correct. if i can get the picture the right size i hope i can get a little help. thanks dell ps head on the right is like the one on the car there are no casting numbers that are readable- the head on the right has a 180 cc chamber, the left is 169. the 28 gasket matches all the bolt and water holes in both heads. the heads are the same thickness- does anyone have any idea what year the left head is? i thought for sure that some one would have sean one before. thanks

Most likely the two heads were at one time the same basic casting - are there casting numbers on the head to confirm that? I assume all the water jacket and head bolt holes correspond between the two. First thing I'd do is measure the overall thickness of the two cylinder heads. The head on the right in your photo appears to be either one of two things; a high compression head offered for that engine (check the parts book to see if such a head was offered) or, more likely, a head that has been severely resurfaced by surface planning or grinding, probably to eliminate warpage - it may have been surfaced beyond a useable limit so I'd be VERY RELUCTANT to use the head on the right without first checking to insure that enough clearance remains for the valves to open without hitting the top of the combustion chamber and bending their heads.
