You should be able to run up to 75hp shot without many upgrades. I would suggest 1 heat range colder NGK plugs, 2 degrees timing retard and upgrading the ignition system. Oh, and you're also going to need a stonger clutch too.
For anything above the 75hp level you're going to need a few more things including converting if you didn't start with a direct port setup. For anything over 75hp you will run into possible distribution problems with a single fogger setup so would strongly suggest getting a DP set-up right from the get go with intentions of squeezing over 100hp. You're stock block and pistons should be able to support 100hp safely.
For anything above that you will need to stregthen the bottom end, with forged pistons and rods and would also suggest getting a progressive nitrous controller like the Jacobs Nitrous Mastermind. Hope this helps.
