I'd rebuild it with some KB/Icon #KB892 pistons and some of Ace's forged rods,zero deck the short block,then sell or trade the #16 heads for some 6X-4's,mill those to at least 89cc's or so,and use some +.100" longer valves in these for more lift clearance,and then run a nice 230ish/112°+4 custom ground hydraulic roller cam in it.
Then you can run straight pump gas,and still have plenty of ummmppphhh to get-r-done.
Should also pull plenty of vacuum for power brakes too.
