home porting E7's

[Skywalkr57]

alright, my friend gave me his old E7's for my bday to port but im new at it. ive had them hot tanked and glass beaded. i want to put bigger valves in, maybe 1.94 1.60 im not really sure. should i port them, then get the machine work done for the valves? what should i be focusing on while doing the job, ive heard mostly exhaust side and getting rid of those bumps or whatever those things are can be beneficial too. i bought the holley systemax I package and put all that stuff in (as you can see from my list of mods) but im not getting the results i want. everyone is just telling me that the cam is too big for the stock heads. this is why i want to get this done. i just want to wake this thing up. i spent a ton of money this winter and didnt gain squat at the track. i went from a 14.4@ 95 to a 14.3@98. the first time is with headers, gears, pulleys, cold air. tell me what you think. by the way my cam has .220 duration and .512 lift. thanks
