Valve Spring Replacement Advice Needed
On several previous threads itís been strongly emphasized how important it is to replace the valve springs on a motor thatís been stored, so thatís what Iím going to do. However, not having a personal engine builder to turn the project over to, I really need some advice. Dual springs, single springs, single springs with dampers, coated springs, titanium springsÖ installed height, seat pressure, rotating vs. non-rotatingÖIím in way over my head and Iíve just been looking at catalogs!
Iím sure a lot depends on the application, but can someone give me some general guidelines on where to start? My heads are stock 351 W, ported, with screw-in studs installed, the valves are oversized Chevy swirl-polished (height identical to Ford), the cam is a Moon solid lifter modelóIíll get the total lift spec tonight, and the rockers are Crane 1.6 rollers. The springs in right now are oem 390FE Ford single coil with dampers.
I feel more like I do now than I did when I got here.
