PRS Aluminum crank pulley & Supertech Master Pack

[K_Senhor]

Hey guys! I've already been searching here about Lightweight crank pulleys and info about Supertech valves. I want to keep my 3.0r engine naturally aspirated, but I want to do some upgrades to improve power, dont forgeting reliability.
I know that I cant make big power without hading some boost. I heard that some guys here had problems with Lightweight crank pulleys and others choose to install the Pleasure crank pulley without problems till now. About the Supertech Master Valvetrain Pack, what you say about installing this in a NA engine? I read that in Perrin H6 build Blog they were amazed with the OEM and Supertech springs rate diference, since supertech are about 3 times stronger. Do you think it's a good idea to buy the all pack or should I only replace some parts, since I'm not thinking to do Big Power. Just looking to improve a little bit to improve the engine response, have a more linear acelaration, have more torque with a bullet proof engine.

Have you got access to E85 fuel so you can tune for that?

Wouldn't look at those other things.

Sadly, here in Portugal its not so developed like in other countries. In Europe there are few countries with E85. Would you say just Raptor Headers and a tune?
