mmm stroker
TB spacers are a waste of money. Basically an expensive whistle. I'd get a bored out throttle body along with a freer flowing exhaust and intake. Should give you some decent power.

If you're having trouble dialling in your AFR, you may want to consider adding a MAP adjuster (it is used to adjust the +5VDC reference input signal to the MAP sensor, allowing for gross fuel trim adjustment. The HEGO feedback signal can really only respond in a narrow range of operation - if you have trouble, you can bring it closer (having an AFR monitor helps, but they're spendy. Monitor economy instead, and a pyrometer EGT gage can be hepful. And usually costs less and is easier to install...) to stoich using the MAP adjuster, and let the HEGO do the rest.
