whats the difference between version 2 heads and earlier ones ?

The Later version has a larger volume water jacket, a bit of extra reinforcing around the exhaust port and a number 2 cast in the front of the head and above the right-hand inlet port next to a large AM roundel. If I remember right there's something about spring seat height difference as well, but can't quite recall the exact details.

We talking 1850 slant 4 heads here?

If so the early ones have a slot under the inlet ports for 3 and 4 pots. Also a change in IIRC the inlet valve size? Later ones are slightly larger.

I'd assumed Sprint as they asked about a Sprint cam previously, but we all know about assumptions being the mother of all...

Jonners is so awake.
