thanks for the info, sorry if I hijacked the post....my wish list is to eventually hop up my slant, was figuring rering if the bores look good, one of the 2 smallest hughes cams, cut the head .1" or so, a little bit of bowl work, dunno if I'd go bigger valves or just backcut the stockers, I'd like to go with the aussiespeed 2bbl hurricane manifold and some sort of EFI, whether it's the 2bbl holley sniper, or figure out a controller and doing a port setup utilizing some OEM injectors (I do have 16 5.2L magnum injectors on my shelf) and the 2bbl magnum throttle body I have sitting on the shelf, too...
