Let's Build a 416 with Cast Iron Heads and Manifolds

My suggestion is talk to KG engines in Ohio. They have a very decent cnc program for J heads that is very reasonably priced. Then send them to Porter Racing for the finishing touches and cam suggestion.

I think I would just have kg engines do the whole deal if they're doing the CNC work. Makes no sense to send them to another party after that.
