LT1 Valve Springs What springs other than the 918's are yall running on your stock heads? ALOT of people have been having the newer and older batchs of 918's fail over the last few weeks and it's making me really paranoid, so I am looking into other options.
I want a good set of springs that are rated over .600 lift... I would prefer a behive style spring but I am not totally against a dual set up. The rest of my set up consists of 1.6 SA comp mags (roller tip) and hardened push rods with a 230/244 .544/.576 on a 112 cam shaft that I shift at 6850 RPMs.
LOL, yes I know I need to switch to NSA rockers and I plan to do so before I start racing alot more... Any opinons are greatly appreciated!

I run the PAC 1518's. PAC was the company that made the 918's for Comp and had zero issues. It was a company in Mexico that started making them and had issues. The PAC 1218's are PAC's version of the 918's. The PAC 1518's are the same spring but nitrided for extra strength and have a max lift rating of .650" versus .600" like the 1218's do.
