If you're running stock heads, I'd stick to the 1.7's. Your heads really don't flow better up there at almost .650" lift than they do at .612", so you wouldn't see any major difference in power. I'd run the stock rockers or maybe have them modified with the Comp trunion upgrade kit to give them a bit longer and more reliable life

Most off the shelf cams are set to run with a rocker ratio of 1.7 so going to a 1.8 is not a good idea. Also take into consideration how much more lift you are going to end up with.
Bigger rocker ration is just a bad idea all the way around if you are not setting up your engine and valve-train for it from the get. (MY opinion)
The best thing you can do is get an trunion upgrade like mentioned above and you will be good.
