I put Stock ported & milled heads on my 95 5.0. Didnt get much of any power out of it. If you want more power, bigger valves are the way to go. But I'm like you...a college kid on a budget.I'm also sprayin my car with 100 shot dry kit. I blew my head gasket at the local strip because I failed to replace the stratched head bolts. I replaced the gaskets and put new bolts in and I'm using FEL-PRO High Performance Head Gaskets from Advance Auto for like $25 each. They sell specialty gaskets for nitrous and supercharging, but Something a little better than OEM should be fine. good luck.
