Okay guys, I ordered a Supertech valve spring kit (SPRK-M1007D-3). Came with 16 BROWN valve seals with the part number VS-H6.6E.
Called Supertech, they said exhaust seals can be used on the intake as well. Seemed like all was good.
Messed up and didn’t install seats first, so had to trash 8 of them. I currently have the brown VS-H6.6E on intake & exhaust for cyl 1 &4.
Ordered more VS-H6.6E seals, and they’re blue. are these the same as the brown?
I Have enough blue seals to redo all valves, but would rather not if they’re actually the same material.
Look like those blues (exhaust) are a reduced OD spec
they are both reduced diameter. Weird that I got 16 brown seals (two packages) with the brown color, and same with blue. So I’m questioning if color is an indicator I guess
Yes, certainly appears that the Blues are a higher temp rubber compound but whether they are interchangeable w/the intake is beyond me (they show to be the same size so hoping that info is correct about using them on the intake side)
