SE HEADS--Valve seal

[mattdrag]

i am using a set of SE cylinder heads on my new 80" build, is there a problem with the #18046-98 valve seal ? Should i replace them before installation ?  Thanks G

Those heads come with  the K Line seal. They'll probably last you a couple years. If you want to put a better seal on use a Viton. They're more forgiving to loose valve clearances.
