It's time to generate more funds for the ABA swap that's in work.
So... from the spares pile:

a pair of low mileage AMC 1.9 heads

Photos available. No cracks that I can see (I haven't Zyglo'd them,
but I have examined under magnification.)

$350 + postage for the pair.

If you're in the PNW, for another $150, I'll toss in the spare
complete motor. (It's pickup only though.)

I've also got a fair number of miscellaneous loose 1.9 pieces. If you
need something 83.5-85, drop me a line. I probably have it.

It's really easy to fall into the trap of believing what we do is more
important than what we are.
