the 2 things he got correct is that the tors are garbage, and that the +4 timing is good.
the gain from v fore 3 reeds to 4 is minimal, not worth the price. iboosters wont do shit. Stock CDI is the most reliable, aftermarket ones always seem to have issues and wont gain you shit. boost bottles do nothing but tear the intake boots, making a air leak, as mentioned spark plug wires arent going to do anything.
If you want more power, a cool head with a smaller dome will provide more power, but you will need most octane depending on what compression you have.
Porting is the best bang for the buck, all the guys on the forum are good, wildcard, herrs, and fast. right now i would take up herrs on his 100 bucks off, if you mention the thread bashing him on here.
you could also go 4 mil if you want to dig into it.
