Re: FH Valve Springs
Yes, high rpm was what I was referring to as that's where the high pressure springs are need BUT, I'm thinking of making my own guilds out of aluminum (bushing the EX with aluminum bronze) and using low pressure SBC springs and retainers (about 200 - 210 lb open) maybe even PC seals.
My engine won't go above 5500 though.
Why? Just because I can. Also, I can never stop thinking of why something works (or not) and always trying to improve, either by lowering weight, making it stronger or lasting longer. It's just how I've always been.
