That's good to hear. I wasn't that responsible at 20. I think your camshaft will alleviate the 'doggyness.'
Also you could mill the heads .040" and then the intake to match which would reduce the chamber to (maybe, possibly) about 66cc which ALSO will alleviate the 'doggyness.' My apologies for offending you. I believe that you probably have the '675' cylinder heads used both on 360's and 318's with your 360 being a late 70's block.
