Just some pics of DiegoTed's buddy Steve's sb eddy heads. I'm gathering pics for our website and thought I'd throw them up here.
Here are the flow #'s at 28" using a 4.03 bore.
Lift Int. Ex.
.200 150 108
.300 213 150
.400 257 188
.500 278 209
.600 288 220

Looks good...how many cubes...just a question..but is slimming down the space between the intake ports a bad place to gain cross sectional area by the pushrod pinch...I don't see any problem with a narrow gasket area between the ports due to compressive forces being greater on a smaller surface are...just thoughts????
Hope itydon't hurt..I worked mine down to about .080 wide but have not seen any degradation of the gasket with 22psi pushing on it.

There are a few tricks to get the air speed down at the pinch. Common wall is good, corner radius can be tighter than other parts of the port. Floor and roof are where you can really slow it down. It still ends up being fast, but if you don't probe the pinch area at the lifts you'll access, you may have a problem with flow at high lifts and also power loss at higher rpms.
These were left somewhat fast because it won't be an all out race engine.

Yes,I'm keeping treack also.Waiting for flow numbers. 
OK....I haven't been feeling so great, so I keep forgeting them at work. I'm going down there in a little bit to talk with a customer, so I'll grab them and post them sometime this afternoon.
They're not much different than what Ryan has on his site.
They topped out at 292 with a 2.055 valve.
Exhaust flow is a little weak, due to the edelbrock valve. But we may go to a tulip valve, so that will pick them up.
