3946074 GM BBC Aluminum Head L88 ZL1 69 70 427 OEM GM:
$558

This is a factory GM aluminum cylinder head for a Big Block Chevy engine. The part number is 3946074. This head has rectangular intake ports, round exhaust ports, and open combustion chambers. This head was installed by GM on the following applications: 69 L-88 427/430HP engine, 69 ZL-1 427/430HP All Aluminum engine, 71 Corvette LS6 454/425HP engine. This is a very rare and desirable cylinder head.

This head is in very good original condition over all. It has never been polished and both Winter's snowflakes are intact on the outer exhaust ports as shown. The heads have also never been ported or deburred. The ports are completely stock. The head only has one issue that I know of. It looks like it dropped an intake valve at one point. When the head was repaired, it looks like either the guide was installed at slightly the wrong angle or the seat was installed a bit off. I slid a valve in to show how slightly off it is. The guide will need to be changed to the proper angle or the seat will need to be moved. I imagine most competent machine shops could handle this task. The last picture shows how the valve does not properly sit on the seat. Other than that this is a excellent head that has not been ported, excessively milled, or otherwise altered.

This is your chance to get a very nice factory GM high performance aluminum cylinder head at ! That's right, the high buyer at the end of this sale will win this head! offer early and often to establish your presence.
