GTP stage 2+ heads for sale AS in the title...I was going to use these heads on my 408 but have decided to sell instead. They are GTP stage 2+ heads that were put on the car last winter and made 463/402 on a mustang dyno using a TR T Rex cam. Heads are 317-320 CFM and were $2,800 new. I need to sell these ASAP so I will let them go for $1,000/buyer payes shipping or meets me to get them. No lower offers please.

Gallant Technical Performance. They are a company down in Texas. The web address is www.gtp-racing.com
these are the summaries of the stage 2 and 2+ heads:
"Competition valve job, 2.02/1.57 valves, fully ported and polished then flow bench tuned for 305/215cfm. At this stage, we also install better parts: GTP custom springs, spring seats, titanium retainers, locks, and valves. More attention is paid to the finer details of the way a cylinder head flows and how high velocity is made. These heads have produced 455.3 hp | 418.2 ft/lbs and 431.3 hp | 417.3 ft/lbs on two different shop cars."
stage 2+ :
"This stage is just an increase over stage 2; utilizing more aggressive port work to generate higher cfm without sacrificing velocity. This stage raises your flow numbers to 320+ intake cfm and 225-230 exhaust cfm. While researching the LS1 head, we discovered this setup, and have become consistent with the results."
They have approx. 1500 miles on them.

I believe the casting numbers are 241. I imagine they would work really well with the MS3 cam. Originally I had a TR 230/236 cam in the motor with those heads and made 420 on a mustang dyno before switching to the T Rex. With both combos the car pulled amazingly well.
