i have a a15 head ( i think not to sure)
will it fit my 1200 ????

yes

edit: will need an a15 intake manifold

depending on age, oil feed to rockers may need modding, depends dissy at the front or in the middle..

i have a intake manifold to suit twin webers but i will be puttin carby of a motor bike.
im not sure what the head is off but it all looks the same as the 1200..... the motor the head came off was out of a datsun cherry

sure it's not a GX or a12t head, you might be in luck!?

new head on old block has no oiling prolems, but vice versa ya need to drill a new hole!

Might have to do what I did with mine, put the A12 gasket on the A15 head and mark the oil hole that feeds to your rockers and then drill a 45 angle hole from the bottom of the head towards the hole where the head bolt goes threw. I did this swap to mine and didn't have lubrication to my rockers until I noticed that the A12 doesn't lubricate the rockers like the A13,A14 & A15 does. I drilled the hole and it took care the problem for me. Good Luck.
