Has anyone installed 78070 Hedmans on Performer RPM heads? - 05/22/23 10:54 PM
Been awhile since I posted but I'm currently in the operation of upgrading from HP manifolds to hedman shorty 78070 headers on a 69 Charger. It's been a battle so far I had to take the bolt off the motor mount on the driver side lift up the engine one inch, remove the mini starter and I'm currently battling the installation of the header. I have a fitment issue because I have performer RPM heads on this 440 and it seems that the flange of the header is hitting the head stud at the far front of the engine and at the far rear of the engine. Has anyone installed this can you give me a pointer or two. I'm looking at the flange and I might have to grind off about a quarter of an inch at the front and another quarter of an inch at the rear to clear the head bolt. For what it's worth I'm going to be using Remflex gaskets and split lock fasteners for the headers.
The only other fitment issue I'm having is the oil dipstick tube is in the way I had to disconnect it from the ear under the number 3 cylinder.
