The 3MA10 cylinders from the MJ 1990 3MA3 also have low timings (192/126), but a wider C-port and a more rectangular A-port what makes it difficult to get the triangle shape of the aux export and so the required blowdown..

A wider C port is not optimal ,and means the B rear wall cant be moved around as much.
The big issue though is the dumb rectangular Aux port - even looks like the useless 4DP.
You would have to weld up 1/2 that port to get the triangular shape needed to prevent vertical short circuiting , and reduce the effect of port linking
to the A via the small end hole.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

The 3MA cylinder I have looks like just like the one 41juergen posted. I think you have helped make up my mind, The 3XV seems to be the one to use.
Compare Pornography now to 50 years ago.
Then extrapolate 50 years into the future.

Re spark plug projection: Removing the plug washer is a trick used in karting to get the spark closer to the center of the combustion chamber. I have no data on how much if any this helps.
