Awesome numbers man, And I'm glad you like the setup!
This is a very similar setup to what I will be going with. (The shortblock at least)
Good Job Man.

Nice numbers. I'm working on something very similar to your set-up. I too am stuck using my Patriot LS6 heads-59cc. My cam is smaller than yours though, since this will be a DD for awhile. Hope I can get my numbers up there with yours.
Mine'll be a 418 though, with the 4.100" Stroke for torque.

Nice results Mr. Martin! Don't sweat the heads too bad, just have fun with what you've got for now and get them when you've got the extra $$ to throw at the combo. Let us know if we can help with ported GM castings, AFR, or TrickFlow heads down the road!

Excellent numbers for the setup! That car's gotta rip!
Like they said, don't sweat the heads for now, enjoy what you've got. Once it gets boring then throw the heads on there and get silly

Picking up 59hp/40ftlbs over the current setup with a head swap??? No chance!
I'd bet it'd be closer to 20/20 or so!
