okay Boys and Girls...
here are the loooooong awaited "impartial" Bulldog flow test
results.
this is a set of heads that was prepped by MM, so im not
sure you could say these were exactly how you'd get them if
they had come from Bulldog themselves, but im sure the numbers would be close.
after i pulled the valves and poked around the ports a little it was obvious i was going to have to flow a left and right intake port, since the final approach from the floor/short turn into the bowl was noticably different between the two(in this case, #1 and #3 cylinder position).
#3 looked/felt like it would be a better port...and it was.

as it turns out.....that difference equates to a fair amount of difference in flow as well.
these heads will only be getting a minor amount of work done to them, so it will also be interesting to see if these two ports get closer to each other after the work
is completed.

the valve seats look like they were probably prepped at MM, since they appear to have been finished using stones.
the intake valves are back cut, and the seats are about .060 wide for the exhaust, and .080 wide for the intakes.

there is some very minor grinding in the bowls and port entrances, but no more than what you get with an out of the box Edelbrock head.
i dont know if this work was done at Bulldog or MM, but in any case its about 5 minutes work per head, tops.

okay...so you probably wanna see some numbers now, huh?

aaaaallllrighty then.......

lift-----#1I/#3I/#1E
.100--67.4/-68.0/55.7
.200-140.0/140.0/101.8
.300-203.7/206.1/141.8
.400-249.9/256.3/175.8
.450-270.7/278.7/187.9
.500-283.6/293.2/196.4
.550-281.2/291.9/204.9
.600-281.2/295.5/207.3
.650-286.6/297.3/208.5
.700-288.4/297.3/208.5

the lastest words that have been thrown around is that these were supposed to be flowing around 20-25+cfm more out of the box than an E head.
while the "big number" isnt 20-25cfm better than an E head, the better of these two ports is about that much better in the .450-.550 lift range.

the next thing to determine is....how well do they respond to some reworking and detailing of the bowls and ports.
