Thank you Brett! This is the 1st time I looked at them on a big screen, my phone did not let me see as much of the cool details.

Working with him has been a pleasure. I am sorry that this is a bracket style build and I am not swinging for the fence (yet laugh2 ) but this is my learning a new engine and get the new car running package as he knows.

I just picked up my smallblock parts to put my Dart back together and my Indy 360-1s are nowhere near as interesting. That refresh has now become a chore to do, so that when it is back together I can play with the new cool stuff heads and intake.

Any spring seat thickness checks? Not trying to be a Debbie Downer but some guys say they're thin. Those look sick btw.


Mopar to the bone!!!

Those are pretty!

Not that it matters in the long run, but will the cnc lines be blended in?

It doesnt look like Brett took much from the spring seat area at all.

I really like the sunset in the exhaust port. They look very nice

Yes spring pad only lost little just to blend into port.
We backed down the intake port little from proto type port.
Rod did sacrifice a head to cut up not much room to play in this casting.

The chamber on that head is different than my 6.4 heads. That chamber looks more like the Eagle head chamber
