Cams for 318's

I know this is venturing into a different topic, but seeing as head choice is important for choosing a cam, I think it's relevant.

Is the #2843675 casting a higher compression head? It's from the pre-smog 318 la's. It lack the heart chamber and swirl ports, but I have read where successful builds have been done with it it, the Comp xe-268H and keeping the stock converter. That's larger than I think I would like to go for a cam, but are those heads a viable option for raising SCR with milling or any modifications?

No, the 675 heads are an open chamber. But they are simpler and flow better stock than the stock 302 heads. You can always mill MOPAR heads for compression. @318willrun has threads on using 675 heads.
