Hey guys, anyone know anything about this style of valve spring? Came out of a stock 8050 engine. Has the regular outer spring with a flat inner spring wound the opposite way. This is the second motor i've had these in. ------------- 7095-685I at 255hp, 8070-225HP,8050-210Hp,8030 with 155HP,220 with 670T engine with A-pump, 7580, 185 with 140HP, 2-6080's,6070, S4 D17,wd45,CA,st34 agco, S1 D17 with 3500MK2 |

I think those are the original style, outer spring with a damper inside. The new ones are a variable rate single spring. The coils are closer together at the bottom than they are at the top. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

| That style is on the exhaust of my 7060, but not the intake. Dont know when or why it got that way, just know how it is now. |
