Edelbrock 2.055 (30 degree back-cut) testing

Have you ever done any testing with a 30 degree seat & valve face? I know it's not the best HP setup but I read an article where Dulcich suggests it... He says it improves flow from .100-.400 without hurting flow at higher lift much.... He went on to point out the valve sees that .100-.400 range twice for every one time it sees max lift so gains down low can have a bigger effect than max lift flow... He only suggests doing it on the intake side.... I thought it was an interesting idea... Especially for guys like me who only run 550ish lift cams....

I am sure you know this but anyway some Pontiac engines ran a 30 deg seat from the factory.

I asked about using it on a low rpm big block in a speed talk post. Wound up speaking with Mike Jones himself and he said just run the 45 with his cam.

This was the consensus most of the others had reached prior to him chiming in as well. Talk was the better flow did not translate to better numbers on the dyno.

I am all ears if someone else chimes in with their experience.
