Try a few of these out next time.

From what I can decipher, you chose to not drill and tap your block to fit the 302 dogbone. If you want to run roller lifters, you're going to need to get the retrofit lifters with the connecting rod in between them. Since you're starting with a non-roller block, this will require you to get shortened pushrods. Summit or Jeg's can help you out with this.

As far as what cam to use, your options widen once you use the roller lifters. It's still up to you though to choose. What kind of powerband do you want? Are you looking for more low end grunt to get you going, or high end power to keep you going? Keep in mind though that the stock 1.6 rockers won't be able to take much more than .550 lift.
