The 452's have never been flowed. They have 2.14/1.81 valves, and were professionally done by a guy named "Spider" that has since passed away. My local machine shop did some work on them and commented on how goood they looked, but they're 452's. Looking at Dwayne Porter's tests tell me that the best of the best 452's don't flow what an out of the box Stealth will flow. I would still be using these heads on this motor if it were not for the worn out header bolt holes that leak pretty badly. I realized that some of the leaking is coming from a freeze plug that's rotted. Hopefully that is the only issue and I can use them on my son's '64 convertible.

As for the other brands of heads, they were not an option as i wanted the stock appearance that only the Stealth has. I'm not trying to fool anyone, but let's face it, I don't have a bar. 11.50's is all I'm allowed to run anyway. Was hoping to get it sorted and put a 10.99 slip in the glovebox and go get some ice cream...ok beer!
