They should be fine, but I'd get a PR length checker, its only 20 bucks. I bought one from comp, and I still ended up using 7.4's. Its just piece of mind. If something were wrong after the build you would know that it wasn't the PR's length.

I went with 7.425's, but 7.4's should work just fine.

Proper way is to check them it's the only way to be 100% sure. Do it right, it's not expensive or hard.

If you want to be sure check for proper length is really the only way to be sure and for best performance. You should also look into a 11/16 or 3/8 push rod rather than the 5/16 push rods. There's a little power in the bigger diameter push rods over the smaller 5/16 diameter.
