Are you going NA or turbo (I am guessing NA with a carb setup)?

If so, I would not buy a template, or 'tools', just get a few carbide burrs from Summit or JEGs and clean the factory ports up a little, the Pineapple Racing templates are really too big for NA. I have an engine that was proted with them and they delay the intake closing WAY too much to make any NA torque below 8,000 RPM. This is a setback because you will need a pretty special intake manifold and really good runner flow to get air to the engine at that speed.

Seriously, just clean the stock port up a little and work with that. Your WHp, torque and drivability will thank you.

Pineapple racing templates are good for turbo applications as they lower the dynamic compression ratio, allowing you to run more boost.

Don't forget that the intake runners make as much difference in power and volumetric efficiency as the ports, the only difference being that properly sized runners don't kill your low end torque (although they hurt it a little) or your idle quality.
