I’ve always used the ones that came in the engine gasket kits , they are the ones you’ve listed above.

Like these? Looks like there’s a different part number for intake and exhaust View attachment 486861

yep those are they, and yes 2 diff part numbers int and exh

 

[Fastereddie]

Thanks guys, i’ll get em ordered!

 

[Fastereddie]

Slight difference in bolt location haha.

 

[Fastereddie]

Got er all done. Noticable difference.

 

[Fastereddie]

No more vibration through the shifter or any road feedback.

 

[Fastereddie]

Going to start doing valve guide seals.
R43TS
What cha guys think? Too hot? Go to a R44 or 45? @Bent77 @Wes Harden
Or just put some new 43’s?

 

[Fastereddie]

Looks nice in here though. 159k

 

[Wes Harden]

43 are cooler than 44-45 that color looks pretty good to me.

 

[Bent77]

I’d go 44. may help with the oil

Oh, I was thinking like ngk then.
I just saw the blister on the porcelin and wondered.

Hopefully there wont be any oil after I do the seals. It only smokes on startup

 

[Bent77]

Ngk is fine. I use to do fleet service. Zero failure from autolites or Delcos

I’ll definitly stick with ac delco. I just meant i was thinking the lower the number the hotter, like ngk is. I run ngk in all my jap bikes and quads. That is oem for them.

 

[Bent77]

Yeah plug numbers are AFR
All over the ****ing Road

Man, i’d rather swap the whole engine than do valve guide seals. I did get a new tool from summit and thats making it alot more manageable at least. I got the driver side bank almost done but keep getting side tracked with girls sports haha. I might have it done by the end of the weekend!

I always figured that would be an "embrace the suck" kind of job. But you'll be happy when it's done.

And "side tracked with girls sports...", if I didn't know you have daughters, I'd be really intrigued what you meant by that.

It is definitly not fun by any means. But I believe it’ll be worth it. Engine runs so well other than the startup smoke. The old seals coming out are pure toast.
