I would like to think that the golden years were when I was running in the late 70's and early 80's. When I was torn down on a protest, Ken Barrett said he was actually surprised at how legal my car was! These were the years that stock pretty much meant stock - and it was fun!

And checking a box of rockers for most lift, the list goes on and on. The Chevy dealer we bought from used to let my wife come pick up every casting they had on hand of the casting number we needed, I flowed them all and returned the ones I didn't want. Same with rockers. TRW springs lasted better than the GM springs. Checked the same new, just lasted longer. That was when the GM dealers actually kept head castings on the shelf. You have to order anything like that now, at least from the dealers here. They have plenty of cup holders, floor mats and calenders.
