Probably run a lot better with Trick Flow heads on it but that would mean that you would have to sell the heads and rockers and buy some Trick Flow heads. Good news is that Trick Flow heads aren't very expensive so you might be able to swing the deal and not be out too much cash.

If you do put it together with the -1 heads it will run okay, just probably be a little soft on the bottom end. I remember back with the -1 heads first came out there were a lot of guys at the track with 440 engines who went pretty slow with those big heads. Sometimes too much is too much.
