    I had a chat with a more experienced chevrolet big block builder, and he thought I still had too weak valve springs. I found a set that should fit the bill. Set of allmost new Edelbrock #5745 springs. With those, I should have 130lbs of seat pressure and 330lbs of open pressure. I started to change the valve springs again and I´m glad I did. Number 8 cylinder´s exhaust pushrod was eating it´s way trough the guide, so I have to replace atleast 1 guide. I think I should replace them all, but aligning them is a motherfucker. All the others still looked good, but that 1 giving up sure doesn´t raise my confidence on the others.
