Patriot, Crane, Comp dual valve spring specs? I have s et of the Crane duals and i know the specs on them (112@1.8 & 352@1.150) but am wondering if anyone has the specs on the Patriot duals and the Comp 921's. Resaon I'm wondering is I'm going go swap to AS 5.3 stage 2.5 head from my stock 02LS6 head. I run the comp cams XE grind 228/230 .571/.573 on a 112. I currently run the Manley Nextex single with Ti retainer with NO problems at all-6900 and no sign of valvefloat(peaks at 420@6500). See the problem is the LS6 head has a hollowstem valves while the new AS's have a 2.04 valve. I'm wondering if the extra weight of the valve may cause any valvefloat problems. The Cranes are only 112@1.8 at the seat while my Manley' were only 115@1.75. I just want to cover all the bases so I don't run into any problems later. Thanks.
