All pro's are a new casting made by All Pro.
They do all GM castings.
They come just as you see them with no parts.
Here are a couple good links to read.

More info thanks to ROB@ASMotorsports
Intake
.200 130.4
.300 196.8
.400 244.3
.500 277.7
.600 293.1
The exhaust numbers impressed me
.200 109.8
.300 166.9
.400 214.0
.500 232.6
.600 246.9
.700 254.3
This is an "as cast" head, no porting. I was told there is enought material in the intake runners for a 300cc head. Talk about a head that will grow with you!
SPECS
Intake port 230cc
Exhaust 88cc
Chamber volume 64-72cc
Intake valve diameter 2.02-2.10
Exhaust valve diameter 1.57-1.60
Valve length stdto+.100
OPTIONS
Copper blended seats
7mm bronze guides
O-ring machining for valve covers
FEATURES
3/4" + deck thickness
Improved water passages
More room for increased porting for the newer 421ci + motors
Reinforced for supercharged and NOS applications
Large spring pad suitable for up to 1.625 springs
Strong reinforced rocker pads for less flex andfits updated shaft systems
Large diameter magnum valve seats that will accept up to a 2.150&1.625 valves
Longer, more stable special removeable bronze guides for std 8mm & optional 7mm valves
Suitable for offset pushrods/rockers for a wider port thru pushrod area
Raised rocker rails for improved rocker arm clearance
Specially designed for excellent flow "out of the box"
Redesigned hi-flow chambers
Longer intake face available, so milling head for small chambers is no problem's.
Pricing will be around $1750 w/o parts. This is an almost 300cfm as cast head minus parts (seats and guides are included). For roughly $400-500 more we can sell them complete.

Excellent looking heads. i think I will try a set of these later in the year myself! We are going to give one of those sets a valve job and flow them stock. And then start hogging them.

The ports come as cast and have a lot of beef in em for some serious porting.
Word is they are capable of flowing 370 -380 CFM.
They should work very well on a big stroker motor

I want to see some extensive port work done on these heads. I'de like to see some .600 numbers over the 350 mark! The lower numbers don't look to shabby either for Pre-ported runners.
I'm in the market for some good heads and I'm looking to make 550hp at the rear tires.

The intake numbers don't look that impressive for a 230cc head. The fact that they can be hogged to 300cc's makes them very nice for the big cube crowd though. I don't think they will be that popular in the 346-383 crowd. I believe the exaust numbers are with a pipe. That's why they look so high.
