Got the crossover drilled and tapped. 20 bucks was worth it since I would have to buy a drill bit and the tap, and a handle for a tap that large.
They did an okay job. It isn't straight, which I don't understand, since there is a flat spot and it is parallel with the the other machined surface on the other side, but it is already on the car, waiting 24 hours for the RTV to cure is killing me, but I will do it since I have another vehicle to drive. I have to fill it coolant, put in the thermostat and the heater hose at the rear of the intake, and drive drive drive (unless it leaks leaks leaks).
