Okay, then YOU name the damn things!

Right now I got a couple questions: *VW heads are nearly pure
aluminum. *I've got a pile of the things but odds are, every single
one of them is worth a $25 bill... or will be. *Point is, I don't much
care for the idea of cutting them and melting them down.

VW head cores are worth that much!? I've melted away a fortune :-(

When I make something SERIOUS out of aluminum I usually use old
pistons, which is a pretty hard alloy with a MUCH lower heat-transfer
ability than VW heads.


So what's a good alloy? Ideally, something cheap & commonly available
(and doesn't say 'Coors'!)


IMHO anything that would fill the mold and not shrink too much would
be usable.
Late model automatic transmission cases work for me. Pours like water
and machines clean.


If I were doing it for sale or use by another I'd probably spend the
money on fresh ingots.

Second question: *Rocket Man heads needum' rockers. *I wuz thinking of
using Chebby *1.3 break-in rockers. *Any better ideas? *(Or rather,
any ideas at all?)

Chevy would be my choice as well, but given that they may not make the
year maybe we should be looking at Ford parts :-)
There will be a demand for after market small block Chevy parts until
we run out of oil so that is where we vultures should be looking.

However I've been trying to remember since this thread popped up where
I ran across some nice rockers that had built in hydraulic lifters not
much bigger than the adjusting screws in a TP IV..
