The pushrod holes need to be elongated (oval shaped) before swapping to 1.65's - so you don't want those until you do the other work necessary to run them. The 1.65's also increase valve lift by 10%, and everything must be taken into account.
The 2802 is going to require a better spring than what is in the 50 year old engine. Also there is much much lift with this cam, and you will be at or beyond coil bind with stock springs. My spec sheet on the 2802 shows .465/.488" lift while stock cams were around .408" lift.
