what are the hp improvements you guys have seen by just geting better heads with the stock cam? gimme some ET's improvenemts if you have them...hp figure...sotp's...
Right now it would be easier for me to put a set of heads than change the cam...don't have a garage, and have not time....

------------------
85 Z28, 355, edelbrock base, SLP runners (old style) 58mmTB, ported plenum, stock cam, fuel reg, TES headers, flowmaster, 3.73's, shift kit, MSD 6a, 305 hypertech chip (YUUUCK!) best prior intake mods: 14.6 @ 94, 2.02 60' temp: 78deg, 80% moist, on radials.
69SS, black, 3,73's, TH400, 402 BB, roller everything (solid 246@50 622 lift)+stud-guirdle, 67 Vette heads ported and o-ringed, about 10:1 cr KB pistons, should be done this summer, goals: 500hp and lots of fun

 

Probably 40 HP with AFR 190s, but you'll really need a cam change to take full advantage of their flow potential.
