ok, i will soon need to chage out my set of valvesprings to a better set and i refuse to pull the heads, so how do i go about changing them? The one procedure i saw was to put like 15psi of air in the cylider and chage those 2 vales springs, then move to a different cylinder, Is that the best way? or the only way? lol. if so, where do I get a air fitting that screws into the sprak plug hole, and can i just use a bicycle foot pump to fill the air since i dont have my compressor yet? I also assume i'll need to get a valvespring tool that bolts where the rockers go so i can compress the springs. any specific advice/help would be appreciated, oh and for all intents and purposes its an LSx based engine.

also does anyone have a late model GM valvespring compressor i can borrow or rent.. it is $100 from summit, screw that
