I was talking to a friend about a set of GT40P heads he has and he was telling me that the stock springs are good to up to 700hp, how true is that and shouldn't there be a RPM rating as well?
Thanks

Time to get new friends. Valve springs aren't rated for HP or RPM. Do a search here or look at the anything/everything gt40 thread on the other forum and you will find what you need.
Sounds like a girl i knew back in the day that thought the button on the shifter of her Naturally aspirated eclipse's automatic shifter was for turbo boost. Turns out it was to turn over drive off, lol.

I'm not gonna lie. When I'm in the truck on the highway and I need to drop a gear to get a little power, I hit my boost button - I mean, turn off my over drive.
