Thanks for the info... I bought my heads 2 years ago and have been wondering about'm. The motor feels much stronger compared to.. ported to max wedge size 915s it had. But that doesn't mean much.

I would say it's about an average port job, some enlargement but no welding or epoxy or brass to put it in the wild category. Actually the flow is from two heads ported by different people, but the flow numbers for both were within a few CFM at all points. The orange head was said to be ported by Lee Shephard, but there is no documentation to prove that. The exhaust seats were replaced.

finally got a chance to dig through my notes.
these numbers are for a set of the NHRA version head.....2.08/1.88 valves.
this is one of the newer heads without the freeze plugs in the ends, but it isnt the latest version with the "undersized" chamber.
also, the valves i used were modified in a way which seems to perk up the low lift numbers a bit.
the valves were out of an NHRA stocker head, so i'm not going to get into the details of what was done.
aside form the valves though, this head is right OOTB.
no valve job, nothing.

this head was tested on a 4.250 bore(426 size), instead of the 4.375 i usually test BB stuff on.
28" test pressure, 3/4" thick radius plate air entry.

lift-----I/E
.100--68.4/57.7
.150-110.6/76.4
.200-150.5/96.7
.250-184.2/116.6
.300-208.6/131.4
.350-222.5/145.1
.400-230.0/158.0
.450-241.2/167.9
.500-249.5/177.3
.550-258.1/184.8
.600-265.5/189.0

i have some numbers for the ones with the freeze plugs somewhere. i'll dig around and see if i can find them.
as i recall.......they werent as good as these.

looking at the pics Randy posted, his look like the latest version, which i would expect to be slightly better than the numbers above.
his is the 2.14/1.81 version, and the 2.14 valve should be worth something.
