Hi. New here was just wondering if anybody had any suggestions or tips for interchanging diffrent year parts to gain some extra power. I am curenlty running an 02 cavy with a 2.2 ohv 5 speed. Starting on an 02 2.2 ohv auto. Just looking for tips. Already read about the quad4 tb. Guna try that with port and polishing head. Any other suggestions would be appreciated. Thanks guys

Can't really do that without a tune unfortunately. Ported head will help but I don't think you'll see much improvement unless you do a full head build, cam swap, and tune. These motors are strong but don't respond well to small mods like the dohc motors do.

On another note, search for the caravan rear wheel bearing. You'll find that the stock jbody bearing is crap and will break on you often in the right rear. Someone figured out a hybrid setup using caravan wheel bearing parts that's bolt-on and much stronger.

You can swap to different ratio rockers on the ohv that should net some more power. If you search in the performance forum, there should be multiple posts about it.
