Indy/rhs heads?

I also went with the Magnum version. I had to because the last guy who had the block hogged out the oiling hole to the heads for the LA version, I pulled out the plugs and set my gaskets on to make sure.........well you can guess the rest, it would leak like a stuck pig so I put the plugs back in and back to Magnum oiling thru the push rods. I already have all the rockers, stud girdle's etc which is a good thing.
