6 Bolt AFR heads A couple of guys said they would like to follow along as we add the two additional bolts on my AFR heads for my turbo engine.
The pics show how the heads look today. The welding around the cylinder is so I can move my o-rings as I am also going to run a larger bore than my old 352ci engine. The outer lug will be drilled for a pass thru bolt that will thread into the block side. The upper build up of weld will be drilled and tapped, that bolt will come up thru the deck.
This is a ton of work to do, but I have so much time and money in these heads it is worth it for me. These heads have already had extensive welding to add strength to the deck and allow for larger valvesprings, as well as porting by ET and larger titanium intake valves and inconel ex. I just went this direction to save money!!

The deck of the head already had extensive welding to help it hold up to high hp runs.
The additional welding is worth it to me if I can squeeze another 300hp out of it. I will be happy if the gaskets will live 40 runs at 2000hp, at least for this year.
The block is a Dart std deck 4.125 bore billet.
