It begins again - 512 Stroker

Thanks for input. Decision was made long ago. My racing days are long gone. This is a "Coffee Cruiser" & I probably should have said that originally. My question still "is there a benefit to the additional flow holes along the bottom edge of the late head". I expect both sets can be made to breath well and satisfy this old school fool.

I applaud your build and completely understand where you are coming from.

Of all the iron heads, the 346 and 452 heads are the easiest heads for the beginner to port and get some decent flows. The first time my son and I built a performance engine we used ported 452 heads on a 451/400 stroker. Poor thing only made 588 lb-ft and 621 hp on 91 octane pump gas. I don't recall us ever getting more than 748 hp with iron 906 heads on a 500" stroker. So as you can see, the iron heads aren't worth a damn.

I believe the extra holes were for cooling around the spark plug area in the motorhome engines. They probably will be of no advantage in your application.

I really like the Studebaker! When I was in high school Pop and I built a '53 for some Bonneville runs but that car never made it to El Mirage or Bonneville. We did make one 140 mph run between Palmdale and Desert View Highlands. Somehow the project got abandoned.
