I’m scared to add up what my blazer has cost me and I haven’t even gotten to the body.

 

hmm, That's no fun man. You get it figured out yet?

 

What's the details on the heads? I see they are 706 castings, But I don't see any specs on there site.

 

Just reach out to GPI and let them know what your trying to accomplish and they will get you taken care of. These heads are a little special lol

 

I am just curious what they did. I don't see those castings listed on there site so I was wondering what did and if there is any specs on them.

If I had to guess, a 2.00/1.57 combo with BTR Dual springs. Do they have any flow numbers?

 

No chamber work to deshroud the 2.0. Maybe not needed on small bores, but def gains on the bigger bores

 

Look closer... They just didn't soften it.

 

you are correct and they have been milled. I would have to reach out to see what the flow numbers are. I'm actually going to do that right now

 

Oh yeah, I missed that AF bahaha

and I call myself a machinist. pfft

 

What CR are you looking for and how big a shot?
