OK Thanx for the info Bronze Bird. It would make sense that after a certain amount of head milling the intake would need to be milled/cut too.

I have decided with the 7K3's missing the outer most head exhaust stud I will keep looking for a set of 6X-4's or my all time favourite edelbrocks at a reduced price. i can wait for a used set. the car smokes the tires at will now with the 455 with the 4X's.

Any luck with your sale? I noticed it was over a year ago you put 'er up for sale (at a very good price i thought)
