Need help finding a valve spring for my 340 stock eliminator engine. I have been using Isky Springs for years, but they do not have enough pressure for the cam I am running now. Installed height is 1.680 to 1.700. Would like 200 to 220 lbs. on the seat. I just tried to install a new conical spring Comp Cams came out with, but the seat pressure is 290 lbs with their retainer. Even with fifty thousands higher keepers pressure would be 270 lbs. Any advice would be appreciated. Mike Coe 5151 G/S
