Well, I think the stockers are 1.79, and the new intakes are 1.94. Not as big as the 2.02, but still larger than the stock reliefs and valves. I would just suggest buy the valve cutter that slips in the head and cut them yourself. Not perfect of ideal, but since you have the heads off anyways. And if you do, then you can get the 185's since you have to cut into the piston anyway. Hard to tell if it will fit, without claying anyways. I guess you have to balance whether you want to chance buying the 165's, and them not fitting with that cam, and having to cut the bigger reliefs, OR get the 185's and do it anyways, and get the heads you seem to want to run anyways. BOY what a run-on.
