Hello GunslingerFIN...I'll give you the long version on my current issue and see if you can help! I finished my engine and tranny swap and upon starting the 318 for the first time i saw that it was smoking a bit ....SO , I couldn't have that ! I commenced to tearing it down to the bone. While cleaning the carbon from the tops of the pistons i saw what you see in the picture and was immediately thrilled to the bone ! It's an old build but it is .040 over and cammed a bit so my old 'Cuda should be a fun little ride ! Here is my problem...i've never seen this type of valve stem seals so i'm not sure which ones go where ! The smaller umbrellas are ribbed on the inside and fit tightly on the guide nipple. They allow the stem to slide up and down without moving out of place so i would think they are intake seals. Maybe FELPRO gave me 2 options for exhaust. Any ideas ?
