1971 Pontiac 455 Head D Port 325 HP 4 Barrel GTO Lemans Tempest Sport. This product data sheet is originally written in English. HARD TO FIND ORIGINAL CLASSIC CAR & TRUCK PARTS. We acquired this head amongst a much larger lot of parts. We had it tumbled so you can better see the condition of the head. It came from a past hot rodder so I would expect it’s been well used through the years. The date appears to be E041 which would decode to May 4th 1971. However date castings can be hard to read at times so please review to be sure you agree. This is a single 455 D Port head that would support 2.11/1.77 valves 114 cc combustion chamber. Expect it to need work prior to usage or installation, do not expect to plug it in and work perfectly. Unless otherwise noted this is a used part. A used part may have dust, dirt, old paint, scratches or cracks. These are not new parts unless noted so please set your expectations accordingly. See pictures for condition and wear as we rely heavily on photos. Applications are based upon various sources, although I try to make sure research is correct it can be flawed so please verify your applications. Please use a PC to take advantage of the zoom feature as it will provide much greater detail than a portable device. Thank you for allowing me to share my passion with you. I have thousands of original car and truck parts available in my store. All of our packages are professionally packed with a custom made box from recycled cardboard. This will take a little longer but you’ll be pleased with the care that was taken with your part. See our other items. Unless otherwise noted this. 1971 Pontiac 455 Head D Port 325 HP 4 Barrel.
