Default New Stage 2 Edelbrock Flow Numbers

We have improved our already popular Stage 2 FE heads with new port designs. We have improved the exhaust quit a bit as it has always been as little on the weak side. This is a street/strip head with a user friendly 45 degree valve job and a conservative 200cc runner volume on the intake.
We can do a 50 degree valve job for the high lift race stuff and get more flow plus we still have our Stage 3 head which I am fluffing up some as well.
The new flow numbers are as follows.
Intake .300/227, .400/276, .500/307, .600/325, .700/336 and .800/344. These are very similar to our regular Stage 2 head but our new port works better .600 and above. The exhaust is .300/161, .400/195, .500/226, .600/249, .700/265 and .800/276. The exhaust now flows close to our Stage 3 head but is a little smaller.
Remember our Stage 2 heads use a 2.19 and 1.75 valve so they can be used on bores as small as 4.140 so they work great on 428 strokers. We also do as version with the smaller 2.09/1.66 valve and they flow about 10 percent less.

Thanks, Keith Craft
