Sorry about that. These are crites headers and the flanges measure 3/8 th. inch thick. Thanks

Thanks for all your replies. This will be the 1st time doing a starter swap on this car. Sounds like going thru the bottom by removing some steering linkage is the way to go for me. Thanks

I have crites headers that have been ceramic coated on my 482 in my 66 Fairlaine. I need to change out the starter. Would it be difficult to pull the slip on collector off? The motor been in the car a long time. Trying to figure out how to make room to get powermaster starter out. Either I have to remove some steering linkage to pull it out thru underneath or remove #4 header tube and pull starter up the passenger side. I've never had these headers apart since they were new. Thanks

I'm gonna pull my 482 out of my 66 Fairlane this winter to fix a few oil leaks. It was built back around 2005.It has a scat stroker crank and I have always had a rear main seal leak. I understand that these early cranks didn't come with the oil grooves cut in at the rear of the crank. I read about these 1 piece rear main seals. Has anyone here tried them? I'd like to hear any info about these seals. Also what is a good oil pan gasket for my canton t-shaped oil pan? Thanks
