I was basically handed a set 4V heads with all timing chains, front covers..... well actually more like a 4.6 4V complete motor without the block. It was free and off of a low miles car so what would be the process of doing this and would it even be worth it. I know about the intake manifold being a pain in the ass but I already have that solved. My main concern would be what acc. pieces to use and what if anything would have to be custom made. Any additional thoughts would be helpful.
