T/A heads

I’m just about finished with this second set.
The “ported” head had the pinch opened up way more than necessary for this build, and also have quite a bit more work to the intake guide boss than I would have done.
Especially on the curved wall side.
They had it trimmed down enough so you could get a 1/2” burr down in between the guide and the curved wall.
I “prettied” the intakes ports up on that head. How much of those 4 ports were worked on varied from hole to hole, so I just kind of finished them off.
I also got rid of the peak at the leading edge of the guide.
After installing the ex seats and re-cutting the intake seats and bowls, a fair amount of additional blending was done there, along with a reworking and rolling back the SSR.
The port openings were “close-ish” to the std intake gasket, but weren’t very uniform, so I brought them all out the the gasket size.
The ex ports just got the new seats blended into the bowls, and then the rest of the port very mildly “cleaned up”.

This is head “B” after the ex seat install, seats recut, bowl cut, and the tweaking of the ports:
