For that price tell that guy to run them on one of his motors for about 3000 miles and then if they do not fail buy them from him, lol!

looks like a small chamber, i'm guessing a valuable number like 12 or 48.

Comparison of 1969 -'70 RAIV chamber (top) and common high-compression '68 -'70 D-port (bottom). They're actually quite different. Pictured here are a 1969 #722 RAIV 400 head and a 1970 #13 400 head.

I have fixed many cracked heads using repair pins like what was done here. Most crack repair pins are tapered and try to spread the crack apart, so it is very important to start the first two pins out past the end of the crack to be sure the ends are completely gone before the rest of the crack is repaired. They generally work good, but for $2900 I would pass also.
The better repair pins are straight, and have threads that are shaped in a way that pulls each half of the crack together. The tighter you tighten the pins[until they break off] the tighter it pulls the crack together. These pins are made by Lock-N-Stitch. Much better system for crack repair.

Believe it or not, the D port heads have a better burn rate since the plug is not sunk down into the chamber roof!
The RA4 chamber does better with dome Pistons .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
