Aluminum GN1 heads

[86bluet-type]

I have a set of 14 bolt GN1 heads. These are off of a stage 2 motor but will bolt right on to a 109. I do not have flow numbers. I drove the car on the street and a few track runs before selling it. It was sold as a roller. They are set up for roller cam

Heads complete with rockers 3800.

I have a set of new GN1 valve covers that I’d add for 4000 total.

Location is SE Louisiana. I ship UPS flat rate only on heads.

Probably over 15 years....

Those are original casting heads because the logo was stamped between the exhaust ports late 90’s.

AIRC, there were 3 versions of that logo location.
First was milled in and created cracks due to insufficient wall thickness.
I had a pr that blew up on first dyno pull.
Next was the raised letters as being in the casting mold, like the ones in the pic?
I also recall the logo being milled on the flat ft surface. Y/N??
