Anyoen know about GM PN#3927142 valve springs?
"NEW GM OEM Z-28 #3927142 Valve Springs. They have an O.D. (stock) of 1.273 with installed pressure of 110 lbs. @ 1.70. They are good for up to 600 in. lift cams. They fit any SBC head. 16 pieces"
I found those for sale. I'll be running a .510/.540 lift flat tappet cam. Think they will work?

"American made baby. 100% American iron. The muscle among the masses. My hero. Yep, you can take your ergonomically designed, space age, computer controlled, 4 door, cup holding map lighted split double wishbone split fold down retractable cargo covered moon roof piece of transportation and keep it. For I have felt the thunder. And I know the difference!"
