Also, depending on the year you may have air rail holes to plug unless you
want to "smog out" a 1300.

The idea is a 1500 head is already set up to run on unleaded gas.

Yes, the 1500 head will fit on a 1300 motor. Basically, (and I only mean
"basically") the only difference in the heads is the depth of the combustion
chamber. The 1500 chamber is deeper and will provide a definite and severe
reduction in compression ratio unless it is shaved an extensive amount
(somewhere around a quarter of an inch).
The use of a 1500 head actually has merit if you can find one with the
larger valves and then do the necessary modifications to bring it up to the
desired compression ratio.
