Choosing springs for mystery cam

LOBE LIFT INTAKE .3360

Will a 918 or similar beehive work for this?

What heads are you running, or more importantly what valves? Also what rockers?

With a GM valve and rocker on the combo, a PAC 1218 spring would do nicely!

Thanks Matt. I'll give you guys a shout tomorrow.

I'm running milled 243 heads w/ stock 2.00 non-LS6 valves and stock rockers w/ trunion upgrades. Still need to verify pushrod length once I get head gaskets taken care of.
