No, but it sounds like a good deal.  *Maybe* too good to be true.

I'd have to sit down and do sum figgerin'... and I'm 2000mi away from 
my stuff right now :-).  E-mail me in a week or two and maybe I can 
help.

They are pretty good quality, but I still am not the biggest fan of the 
design itself.  Many will disagree with me, I know, but I still like 
cast iron pumps...

I used to be a big fan of Rimco's head work, but recently I had some 
BIG oversights happen by them that lead to two engine teardowns.  
Perhaps it was just with my application they were sloppy, I dunno.  
But, when rebuilding a head, it is customary to make sure that the 
spring bosses and the springs are sized to match... otherwise the 
spring walks to the side and makes the valve rub against the guide... 
and the valve eventually seizes.

The problem was discovered by Headflow Masters when I sent them my 
heads to fix them.  What I received back in the mail from was heads 
with the work I wanted done to them, and the best "little detail stuff" 
I'd ever seen.  He took time to do little things often never even asked 
for by most as part of his standard cleanup procedure, and likely 
overlooked by many...

Take care,
Shad Laws
