Re: Valve question
Upon pulling out all of my valves, I have noticed none of the exhaust valves have seals. And I'm pretty sure that all of them had seals usually??!!!???!!!
So thought this would be a good time to get some feedback. Thanks!

Some engines didn't use seals on the exhaust valves from the factory. Sounds like yours is one that didn't.

Re: Valve question
Not only what five7kid said but some engines use different seals for the exhaust than for the intake. Really gets confusing.
Best I can recommend is to do some research for your specific engine and see what comes stock. Then, once you know the route the factory took, you'll know what to do if you want to follow the factory path. That's what I'd do since, obviously, the factory engineers had a reason for what they did.
My thinking is that once you deviate from what the factory did regarding things like this you introduce what I refer to as variables. Absent the science to support the deviation the deviation may work, then again it may not; without the science it's a toss up.
By "science" I mean Research, Development, Testing, Emissions Concerns, something I've seen referred to as "Failure Mode Analysis", etc.
Just my view; hope it helps.
