You'll be up there. Mine made 495rwhp N/A through a 6spd, 3" steel DS, 9" and 325 drag radials with a fairly conservative pump gas tune.

Should be pretty close, my 364 made 470 through a t56 and a MUCH more aggressive camshaft, and bigger diameter headers, not sure if i'd say your heads are any better then my Katechs, but should be about the same at least.
