F.Y.I. According to Lycoming documentation.
0-320-A1A 150 HP @ 2700 rpm c/r 7.00:1.
0-320-B1A 160 HP @ 2700 rpm c/r 8.50:1 Lycomings description "same as A1A but higher compression".

But I do have a question -- can wide deck cylinders be installed on a narrow deck case ?? If so what would need to be done other than replacing the studs ?

I don't think that wide deck can be installed on narrow deck cases. You need longer studs for the hold down plates that go with the higher compression 160hp narrow deck engines.

A2B is 150HP
B2B is 160HP

Just like A1A and B1A

Remember, this is conical mount!!! that means it'll be a new engine mount if you want to go O-360 later (unless you find one of the VERY rare conical O-360's.)
