516 head question

won't you end up,spending more money on heavy iron than something new aluminum, lighter, cooler, & flow much better, I bought a set of 440source heads $1000, had them checked out & they needed nothing. I had a machine shop quote me over $1200 to redo some iron heads. Read that as I had the iron head quote 1st lol.

Yeah but you have to have that thousand all up front to buy heads, while you can pay a little along for a shop to build a set.
