I'm having some smoking issues so while my valve covers are off, they are getting replaced. But no one locally knows what I need. Do I want then improved 0-ring version? Does anyone have a part number? I don't want to order the wrong ones

I didn't see any threads specific to the seals.

 

exhaust valves get these:

while intakes get these:

you can get 8 of each at any local machine shop

 

you should be able to find them at any major auto parts store . the last set i got was from NAPA . good luck .

 

the only 2 set of heads ive rebuilt both have the second one pictured on all 16 valves

 

That's what I'm thinking. I need to check out NAPA. I keep forgetting about them

Is there a reason to use two different styles? It's a old engine that may be swapped out this winter, but I don't like leaving a smoke trail

 

I'm too tired to go in depth this evening. I do this for a living, I've sent thousands out the door the way I said, I've never once had any problem from it. It is correct or I wouldn't say it. If you want the in-depth, ask again tomorrow.

 

not saying its incorrect, just saying the only heads... 2 sets... ive done a complete overall on, only used the second umbrella and 1 also used the orings on top of the valves, and the kit i bought from summit only came with the second set of seals

so from my experience either will work, but you're the pro not me

 

I ordered th complete o-ring set from Summit for the low price of $14.95. They shouldbe here for the weekend wrench turning session.
