Vette(s): 1972 conv., sunfire yellow, blk interior, blk vinyl and convertible top. Off frame restoration with American Speed 383 stroker engine producing 500hp plus a 200hp NOS system. MSD ignition. Hooker super competition headers with chambered exhaust.
Check the numbers on the heads again. Are you sure it's not 3927186 instead of 3827186?

Hi OSSW1,
 
I'm looking the Corvette Black Book for 1970, and those numbers look to be correct. 
 
I have a 70 Vette with a 77 engine in it.  I'd like to find on the east coast what you appear to have successfully located.

Try craiglist it shows city's threw out the U.S and pick one close to you. I found a 70 hood with the wiper door and grill for 650.00 on this site. I just look at it every single day.
