Enginge upgrades

[intel76ligent]

I have a WS6 that I want to enhance. Does Extrude Hone-ing make a difference and is it an easy HP getter?

i don't see how it would hurt on a dry intake as it smooths out the passages and blends the turns better

this is a quote from www.pontiaction.com,
" just a mild cam change, extrude-honed heads and nothing else
has boosted these motors to 470 horsepower"
does that sound right? If it's true sign me up! Also trying to replace the clutch, and Centerforce has been suggested as the best replacement. Anyone replaced this before?
