XMS motorsports has heads available. About $2500 for the parts, plus exchanging your heads. Gains of 85-98 horses.

Their website is pretty much useless as far as finding particular parts, prices, and/or specs. Do you have any additional information or links?

Basically, (877) 490-4967 and ask for Bob McAuliffe

Do you have these heads, or know of anyone running them? I'm curious about the true magnitude of the gains, associated mods, changes in driveability, etc....

Not yet. I need to save some money up. Still recovering from the beginning of semester. He stated that he has put the heads on several vehicles, for dynoed gains of 98 horses. I personally don't have any first hand testimonials yet.

Cadillac Hot Road Fabricators has a number of high performance parts.

They are for custom setups, but there are some nice items that will work on the Northstar that is still in a Cadillac body.
