VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 Cylinder head 346 886

G'Day All,
I have come across a 4 cyl head.........346 886........Single Exhaust port.
My parts book indicates it's for valves ........21/32..... and Series AA & LM............(1927 I believe).
Are these valves signifcantly different then the earlier single exhaust port heads ?
I can't recall off hand the 1928 valve size, which of course would have had the dual exhaust port head (After June 1927 ?)

Thanks for Your time and attention...........Joe............

Hi Joe,
