Doing a cam swap so I figured I’d clean up my Eddy head ports a little more.  I started roughing out the exhaust ports to make them a little bigger and smoother: Further reduced and smoothed the valve guide boss, improved the short turn radius with a more gradual radius, enlarged and cleaned up the bowl area, enlarged the overall port, and raised the roof for a straighter flow path.

Smoothed out the exhaust ports





Started roughing out intake ports and hit with 40# roll.  After I check everything again and go over some more with 40#, I’ll finish with 80# rolls.  Reduced the valve guide boss, enlarged the bowl, blended the seats into the bowl, Enlarged port overall, reduced head bolt bulge, and thinned pushrod pinch point to approx. .055.  Final work will reduce the wall thickness to about .045.  The pushrod pinch point was also blended with a greater radius.

After I get this motor together, if I have any issues with the motor breathing I will send my Eddy's back to you for some work.  You did a real nice job on those!
