T/A heads
I’m starting in on the second set of T/A heads.
This is also a set of “finished” heads.
In fact, it appears they had already been assembled at one point....... as there were remnants of assy lube bunched up around the guides, down in the bowls.
A few odd things with these heads......
Someone painted pretty much the whole head with cast blast paint.
Inside, outside, the chambers, down in the ports....... everywhere.
I think they sat around and started to rust, and the paint was a quick way to hide it.
At some point, someone thought it would be a good idea to port these.
They got most of the way through the intake ports on one head...... then called it quits.
I’d say that whoever did the work on them last did some work in the bowls on both heads...... to blend the valve job into the bowls, along with a very slight touching of the SSR.
The first head(A) is the one that has only the bowl work, the second head(B) has had a fair amount of intake guide trimming, along with removing the pushrod bulge.
These heads have new guide liners installed already, and were supplied with new Milodon street series SS valves.
Head A-
Tested as rec’d, 4.00 bore, 28”:
Lift—— in/ex
.100— 62/45
.200—128/93
.300—186/128
.400—213/144
.450—213/150
.500—206/153
.550—210/157
.600—211/159
This head has basically the same type of job done to it as the previous heads in this thread....... valve job, minor bowl blend.
