E5/E7 or GT40's would be better except for chamber sizes. They would give around 9:1 with flat tops.
Where are you located? I have a set of E7's all freshened with new bronze guides, milled, furnace cleaned and shot peened, seats and bowls machined for 1.94/1.60 valves, new valves and all - but they were for helping a neighborhood kid that wanted to hotrod for cheap and he began porting but only got 1 or 2 ports roughed before finding a cute girl. They're taking-up space and dust here. If you're interested and it helps your cause, they're $150 (less than just the valves) and you pick 'em up or pay shipping.
For a few hours with a die grinder, you could have a nice set. If you don't have porting stands (hold and swivel the head on the bench) I can throw a set in for $40 since they're bolted to the heads already... lol. I think I may have a set of stock springs/retainers I'll throw in free (or use yours), but normally you'd use what your new cam requires.

PS: Oh, yeah. I have a set of Ford Motorsport roller rockers I bought for the kid too. I can make a sweet deal on those as well.
