anybody know the code for 4bbl 326 heads? or where to find them? thanks.
THANKS RB, I'VE BEEN TOLD TO GET THE 6X HEADS OFF THE BIGGER CID ENGINES OR TO JUST SEND THESE OUT AS FOR SUM UNKNOWN REASON THESE HEADS CAN BE MADE TO FLOW BETTER THAN THE 4BBL HEADS. MY PONCHO IS A WAYS DOWN THE ROAD BECAUSE OF $$$ WHICH I DON'T HAVE ANY OF RIGHT NOW. 1ST ON THE LIST IS ONE MORE EXHAUST PIPE.

"140" on the exhaust ports on the outside of the head

The only reason I could think of that someone would recommend the later 6X heads is that they have hardened valve seats and screw in studs, however they would drop compression WAY, WAY, again....WAY too much!!!! The code will be on the center exhaust port on both heads. I'n not familiar with too many Pontiac heads. Two good resources. <a href="http://www.wallaceracing.com" target="_blank">www.wallaceracing.com</a> and <a href="http://www.classicalpontiac.com." target="_blank">www.classicalpontiac.com.</a> Good luck!!! I'm about to install my Poncho!!!
