The fuel system was never an issue before, Magnafuel ProStar 500 pump, with -10 to the regulator, dual -6 feed. This is the car when a previous owner had it. Only the engine and trans is different.

Cam is installed straight up. I am not sure about the max lift at the retainer, Harland Sharp 1.5 rockers.
Install height is at 1.95" spec. Do you think shimming them to higher pressure, to bring the open pressure to what Crane suggests, will hurt anything given that the seat pressure will also go up? If he set them at 1.87" seat they would be 256 lbs, and at 1.26" (.610" lift) 592 lbs. (at what the Crane springs would be).
The cam card also gives conflicting spring pressures. Says a 99885 spring, 215 lbs @ 1.95", and 565 @ 1.36".
I can't say what the plugs look like, he never mentioned.
