I'd keep the beehive springs with a stage II blower cam if i went the TVS route. I think I should be fine as long as I stay under 7krpmsAre you planning on running those beehive valve springs. You might want to get some better ones if those aren't the larger of the 2 that Comp cams makes. Some blower cams with a 114 lsa would be a complement.
Nice find on the parts. I'm going with the Trick Flow heads with the 38cc CC and maybe an edelbrock intake to top it off.
