Here is the dyno video of our 509 that we went from Dart Iron Eagle heads to Edelbrock Performer Marine aluminum heads, and from a Dart single plane intake to a Pro-filer Sniper Jr. intake.
All the details are in the video description. Had a gain of 50hp and 30 ft lbs torque.

I recently picked up an 87 P22 with a built 502. Burke heads, EMI Thunder risers, Bravo XR with external hydraulics and some other goodies - estimate between 470-500hp. It did 74mph GPS on a 23p Mirage prop. I've been recommended to try a 25p Mirage+, I think it will eke out another MPH or two with the right setup. Anything else I ought to look at to kick up the performance? I don't want to add a blower, NA all the way.
Super happy with the boat, it's a wonderful hull and one of the best rides I've ever owned. I'll keep this one a long time.

It is getting time to pick up my project, a 1988 oyster/blue P22. It was stowed away due to family issues, had a Merc HP450 clone pushing it to 72 mph. Have been lurking here to keep up the motivation
Motor is sold, now laying on the shelf is a disassembled HP500 EFI with new Marine Kinetics cam, AFR 305 heads and a blower kit of choice, either Whipple (unfortunately 2.3 liter but I do have 2 blowers ) or a Vortech V-4 J.
Was running it with an XR drive, now I also have a -2 Imco shortie to bolt on. As soon as I receive a new cylinder block I will start the building it up again. The factory HP500 block has seen too much salt, don't want to use it together with all the nice stuff going into it.
