H89 purfection! ;)

Rocker cover off - aaahhh h89 all good. Just had a scare there for a moment with the motor I bought. It had a far bit of pollution gear hanging around the stock carby which made me think it was from a later model.
Not to worry, all that #OOPS#'ll be coming of anyway.

Valve cover off -- reading the casting numbers
or
Manifold off -- measure the size of the ports (small oval, medium oval, large oval, or round port)

So from ouside they look the same ? Is there markings on the head which would tell you or do you need to have the manifold off to see if it has the small port head ?
Cheers D

""67 HP was small-port cylinder head. Came in around 1982""

WHat head did the 67hp a15 come with?

or have the ports opened up and cam change as DD mentioned
tuned with 32/36 weber, headers and good ignition

67 HP was small-port cylinder head. Came in around 1982
Along with the changes D mentioned, the cam is smaller duration. Not a forklift engine. Came in last of the B310s and in the Vanette.

A 'full rebuild' will not change the HP design. Changing the cylinder head and camshaft is what is needed. And then rev it up while you drive it!

Does it really matter which one you get it you plan to do a full rebuild?
I remember someone saying if you get the lower HP varient, to bin it and find a higher HP one.

If you're planning a full rebuild, i.e. bore it out, new cam, new valves, porting etc etc, it would kinda cancel out the initial comp differences?

The,67 would most likely be the forklift variant
