While your lifters are at Oregon Cams, why don't you ask Ken to recommend one of their grinds. They know Fords, and Tim McMaster has used them. Start with telling him how you intend to use your car, what you expect from it, weight, gear ratio, transmission, torque converter stall speed (if equipped with an automatic), and tire diameter. Based on what you're doing, it doesn't sound like you're building it just to drive it to church on Sundays. 

Sending lifters off to Oregon Cams for resurfacing.
