Tony, I would love to sell you a set of heads and the stuff to go with
them, but my vote is for the rebuilt engine.  The bottom end on these
has oil pressure problems with mileage and if you have overheated the
motor enough to toast the heads, most likely you have also hurt the
bottom end (pistons touching cylinder walls, and bearings touching).
AVP is a good choice or Suburban Engine Exchange, or even Chris Corkin
as someone else has suggested.  It all depends on how much money you
want to spend and what level of job you want done.

If you still opt for the head replacement, let me know and I can put
together a nice deal for you.

Oil has been 15-50 Mobil One.  I hate to throw good money against bad, but certainly $2600 is better than $4000 +.
> Before the overheating incident the engine ran well.  My fuel economy has dropped significantly over the last two years, but I don't really understand if that is a sign of a worn out engine or not (O2 sensor replaced in the last year).  I have no compression data, and don't think I can get it with cracked heads.
