I don't use the Source Heads above 500 cubic inch, or even rarely approaching 500 as too much time$$ in portwork to bring them up.....
however,
most of our ootb INDY EZ Headed stuff, or with "minor"cleanups... at 493 to 500 Inch... Dyno's ballpark 625 to 660 HP/Trq using NON Roller Flat Tappet Cams at 10.5 C.R. with  Pump gas.

Apologies here, NOT knocking the Source heads, it's just that as a shop....we have a responsibility $$-wise to our Customers to spend their money where it is BEST applied....and in our opinion only....porting source heads to work on 500" Engines just isn't $$ well spent in our books.
