I think that the bare castings of the E7's I had were thumper heads. I belong to many sites. I dont remember wich site I was on when I was defending the Thumper heads and then someone posted a link to a massive complaint page. Basicly they were saying that the bare heads are good but the thumper valve train sucks.
I use to sing the praises of ported stock heads until I upgraded. Now I see I was just wasting my time and money.
BTW I seen the other day that you also post on DWFstangs.com....Seems to be a good site to buy and sell stuff on.
