Best valve springs?

[Geotrash]

I ordered that book. I will someday build an LS from the ground up.

Me too. Fantastic engines.

Side note: it’s also interesting to me that more and more people with "advanced" cars, including BMW E38s, choose to swap an LS into that car - arguably the best BMW big sedan ever built - to get better performance and reliability. I’ve rebuilt an E38 from the inside out and if I had it to do over again would chuck that troublesome DOHC 4.4L V8 for an LS, too. Lots of bias out there against pushrod engines, and I used to be on that bus, but GM schooled the industry with their LS. I’ve become a fan.
