Hi Ed,
        From what I have read the F2 head and barrels are not interchangeable with the other CB750's, the head was new for the F2 and has deeper hemispheres, the pistons are domed and can only be used on the F2/3.
Checking the F2 and F1 parts books the parts numbers are different, also for the F2 the parts number for the barrels and pistons are different depending on serial number and area the bike was sold to.
Barrels:
12100-410-000, serial, 1006022
12100-410-010, serial 1006023
Pistons
Standard
13101-410-003, serial 2609696
There is another standard piston part number,
13101-410-010, serial 2609695.

Cheers

Thanks Den, I'd read that pistons & head were different but wasn't sure about barrels. Hopefully these numbers will help me source replacement/spare parts in future.
Thanks again for your help,

Ed.
