My reworked heads finally arrived from GMR Performance. Now the fun part begins, tear down and reassembly. She'll be a runner when she's done. I'll keep y'all posted on the build.

 

Any other mods besides the heads?

 

I bet probably could not keep up, but i'll be pedaling!!! Lead, follow, or get out of way. Let me know your spec's please.

It's a GMR Performance, Power Pack 2 http://www.gmrperformance.com/

Should be good for at least 105 hp and 115 TQ, as it sits.
Per GMR there is another level of head port they can do that will make this kit do 120hp and 125 TQ. You have to run a larger throttle body though so it's a pretty high dollar investment for those 15 ponies.
