And if you are looking for additional upgrades in the future then the stock heads are now out of the way which would be a hindrance. Besides you can probably shop the stockers locally and get some of the coin back that you spend on the new ones.

Next up would be that intake manifold - not even sure unless you simply want to compare stuff that you should put it back on with the new heads.

I thought about the intake and I'm wondering if the Performer RPM is good enough. It's one of what I call hybrid dual plane, the top of the divider isn't there for what looks like a .5" or more. Plus an open spacer like I'm running right now. Or are all the twists and turns in the runners going to slow things down?
The Q-Jet is making things tough finding a good intake. Possibly a dominator style with an adapter for a Q-jet?
