HEAD ACHE- is it 1.6 or 1.5?

I'ver had a few problems since buying my 1982 1.5 GL Cabrio. It turned out to have an FR engine code which I have traced to a late 70's Scirocco 1.6GT carb engine. I've bought a Weber 32/34 DMTL carb and realised my car has the Solex 1B3 carb on a manifold with a very small circular inlet (as seen in Haynes Supplment pg. 393). I've since bought an inlet manifold off a 1.6GT Scirocco which appears to be the same as Mk2 1.6 Driver that the Weber came off. Howveer, this inlet manifold has an extra port to allow water to run through the head and extra outylet for water at the side. The manifold on my car doesn't have this so it looks like my car has a FR coded 1.6 Scirocco engine with a 1.5 Golf GL Cabrio head? Is this possible?
I've worked out this manifold and therefore Weber won't fit the head on my car. Is it possible to swap the head and if so what should I look for second hand and at what price? Anyone got any ideas.  

UPDATE! The head has the following numbers etc: 055 103 373 2BR BRAZIL and has the servo vacuum pipe coming off the inlet manifold. Is this a 1.5 head? Brazil? I thought all the engines would be made in Germany?

The FR engine code , ETKA says 1.6Ltr 85HP in Jetta and Rocco. up to 1984.

The head is not listed in EtKA, perhaps this a south amercan part. Etka is european parts database. maybe.

The FR engine has a better block, Most all 1.6Ltr engines had lower compression than the FR and produced only 75HP.

Cheaper heads where made in Brazil for the USA market of the rabbit/Golf.

The head u have probabby have been changed. maybe, also you may have a solid lifter head. A conversion to a hydrolic head could be easly done.

Just a note on the weber u have, you wont need the manifold heating system as this was part of the autochoke as well.

I have converted my 1.6GL from a pireburg to weber, then changed the head out for a Mk2 digipants GTI head. The manifolds fit no problems. head gaskets are all the same. And now have a hydo head on a 1.6GL.

hope it helps

Thanks for the info- the manifold I've bought for the car (the one that appears to not fit) looks like this one ebay:

The car spent most of its life in the Isle of Wight (hence to cool number plate 'LOW') so god knows if was a UK car or eurpoean. It appears to have been orignally right hand drive but previous owner said its got a left hand drive gear box which is why first gear is of far over?!

The manifold currently on the car has the small inlet for the Solex. Is there a manifold for a Mark 1 1.6 carb engine that doesn't have the extra water heating bit so I could use my weber or am I best getting a new head as suggested above? Othe option is to sue the manifold without the water heating- would this affect pefomrnce or just result in the in car heater being sueless?

sure looks like the same one as mine.that will bolt straight on a gti head. There is a rubber mount that sits on the top for the carb to sit on. The GTI head has no manifold heating. Thats really not too bad, but in the real cold temps i think it would be an issue. ive just gone through  a winter with mine, The choke was a godsend tho.
also i have the original exhaust air box heating on my weber. so that helps

Just use the manifold without the water pipes and see how you go. If you have warm up problems or want to improve fuel economy (by speeding up warm up time) then get the water pipes from a donor and hook them up. No need to change the head.

No such thing as a LHD/RHD specific gearbox! If you can get all gears with no sloppiness, leave it alone. If there is some play you can buy new bushes for the linkage.

I've managed to get a Mk1 inlet manifold for a weber 34 DMTR carb which has the same foot print as a the 32/34 DMTL so hopefully this will bolt straight on. The casting isn't brialliant but as long as it does the job. Anyone come across a inlet manifold before with LONDON cast onto the top for a golf?
