My 422 smallblock build

These are 810 castings but we milled the saddles off to run blocks. So basically they are “race heads” now.
Open chamber for 59* block. I suppose I could look for either an econo head or a race head, just need to machine it accordingly. Also, mine oil the rockers through the deck.
I’m just really bummed because I have so much time and money wrapped up in this top end already. Now I’m probably looking at another thousand bucks or more.
I know nothing about W2 heads. But I was just on moparts race car/ parts for sell section and somebody had a set of 208 valve ported W2 heads for sell. I do not know the person selling them. But if you want I can send you the link to them.
