6X-8 Ported heads forsale
 

I have a set of 6X-8 Heads forsale.
These were ported and assembled by Racing Head Service.
On a 455 I ran 12.5's @ 110 MPH in 3650lb Firebird with 3.42 gears. Street Car.
They are dual springs setup for a 292 advertised duration .507 lift hydraulic cam. They need disassembly, cleaning and reassembley. Less than 5,000 miles.
Just been sitting awhile.

Do you have flow sheets from RHS?

I do not.

The porting is mild. Not an all out race head, a good head for a street motor.

Could be a really good head for a turbo engine for someone very similar to what I Run w a T88 and run nines off the foot brake . Is that glyptol? Had that stuff come loose on a 455 w aftermarket capes etc. it’s still sitting in my basement 15 years later. Can go forever or flake like crazy.
Couldn’t tell on my phone if that’s what I’m seeing or not?

Thanks - Measured chambers? How many CCs?

Stock is 98 CC.

The heads origanlly were only resurfaced.
