Mikey,

First, suggest you contact Wilf Leek. He's from UK, runs a DAC, and posts here frequently. He might have some suggestions as to where to get machine work done, and what is practical for your setup.

Second, keep it simple, and practical for a street Cobra. You don't need a solid roller cam for the street, or 10.25 CR for at best 93 octane fuel. Do not mill these heads. Pick a piston that will give you 9.5 to 9.75 CR. Get a warmstreet grind cam hydraulic, hydraulic roller rerofit, or solid flat tappet (if you don't mind adjusting them periodically).On a Cobra, you need to spend you money on suspension, brakes, wheels, tires, and creature comforts.
