2.5 cylinder head
Hi everyone i have a 1984 gtv6 completley 100% original but i was wondering after reading all your comments on engine conversions is it possible to put a modern 2.5. 24 valve head from say a 156 ont to a 2.5 alfa engine

You also have the differences in the oil-delivery system... The 12 valve block has a gear-driven shaft that axtends through the right-side head (from the pulley on that head that powers it), down through the block...
The 24 valve 156 block has a chain-driven oil pump (off of the crank) in the sump and no shaft from the head.
It can all be converted (and as Z said - the valve releases need to be cut on the pistons too...), but it is a great deal of work.

...to Alfa, or not to Alfa? That is the question...
