Single valve springs
#11
Makes me want to swap my 1218's for something safer. The 1218's are rated at .600 and I'm at .595 lift. Is the "piece of mind" with duals a better trade off than the lighter beehives? I've read where the PSI 1511ML beehives have had very little failures, one post over at tech saying zero, I kinda find that hard to believe. They cost the same as the popular .660 dual kit.

As 03serraslt stated it went back through the intake manifold. If it's a stock plastic style intake, Just throw it in the trash. Don't attempt to reuse it. It could cost you another motor. Particles can get trapped within the manifold you can't shake or wash out.

100% stock setups seem to do fine. I ran patriot Gold duals for years, then my 370 has PAC something. 440 seat pressure and like 700 lift. I forget the PN.
