Hey folks I have a question about what valvesprings to run for 20+ psi of turbo boost on a 2.4 with an 086 head with W41 cams?
Clevite HO Springs i would think
take a HO spring to a re-builder and see if he can set you up with a little stiffer.. 20PSI trying to open it.... i would want at least 20# heaver seat presser.

That's what I'm thinking Chris and 105# on the seat shouldn't wipe a flat tappet cam, but who makes such a spring?
