Thanks Ross, your Mustang is a sweet ride, it makes wonderful music! Thanks for the follow-up on the valve seals, I'll give them a look. The curve in the Mallory is bone stock, I've got an old Sun distributor machine I need to get playing on...
The valve seals will likely be accompanied by fresh valve springs, the RPM intake, and a recurve on the dizzy. Now to make time to get it done.
