516 heads on a 470? If you are going to use 516 heads then just do a stock rebuild on the 400. Use the factory cast crank and cast pistons and it will last 100,000 miles.
In the future when it comes out of the ramcharger, I'd like to be able to put new cam and top end on it with aluminum heads and put it in a duster.
Currently the 400 has lots of blowby, and needs to be rebuilt. So, knowing what I want to do with it in a year or 2 with the duster, I don't want to have it rebuilt to stock stroke now then have it rebuilt again with a stroker kit, I'd like to take care of the bottom end once.
