143 Pontiac heads off 67 400 motor. These were rebuilt and ran on car for less than 500 miles. The rocker arm bolt holes were tapped for screw in studs instead of pressed in. Hardened vale seats were installed to run unleaded gas. the 143 heads were on 290, 325, 333 HP engines and were a 10.5 compression head. They have 2.11/1.77 valves and 72 cc chamber. I ran these heads for a short time on my 67 firebird after the motor was rebuilt along with the heads. A local shop did the work on them. I changed them out for some 6X heads and no longer need them. They are ready to bolt on and run. I have more in the shop work on these than I'm asking for them. $325 <a href="http://s997.photobucket.com/user/Nealgd_photos/media/1967Pontiac400heads017.jpg.html" target="_blank"><img src="http://i997.photobucket.com/albums/af94/Nealgd_photos/1967Pontiac400heads017.jpg" border="0" alt="143 pontiac heads photo 1967Pontiac400heads017.jpg"/></a>

So the holes were tapped...but do you have the screw in studs installed? How bout the springs, how much lift can they handle.

Also how do these heads flow compared to other Pontiac heads such as #16's, or even 62's, ect?

Any additional pics?
