Start by replacing the K&N with an OEM filter.
Then cams would be a good bet.

Email the various cam manufacturers and ask them what grinds they have.
Or you can have yours ground to suit your specific needs.
The 954 pistons are already very light so I can't see much to be gained from a complete engine tear down just for that.
How much mileage is on the engine?

Then there's certainly no reason to be opening the engine up.

Cams, OEM filter and remap to suit.

What are the sleeves you list with the piston kit?
I would think that'd get you pretty close to the 150hp you're chasing. The high-compression pistons and head work won't get you much - especially considering the cost of stripping the engine to install them. I'd suggest just dropping the cams in and see how you like those before pulling the head or stripping the engine.

Re: 954 mods

Don't forget to add the cost of sixteen new shims for the cams.
About $100 for the set.

What is wrong with the K&N filters? This is the 2nd time in 2 days I have heard about this. (Other guy was talking about getting dirt in carbs with them) Seems like a sure bet that the higher flow would give an increase in performance.
