The head should not make any difference. The difference is in the valve train ( cam, lifters, pushrods, rocker arms, rocker shaft). You can run either head with either valve train. But you must change the "complete" valve train. Also, you must run the correct valve cover for the head used.
That's true. He made no mention of whether he got the tin. ......and those valve covers are gettin tough to find now. I'm still lookin for a solid lifter cast cran rebuildable core, myself. They just ain't out there.
