If your valve guides are in good condition you'll probably be ok with out them.

My engine builder used vauxhall xe stem seals I think. They are rubber rather than the plastic so hopfully will not crack at high RPM.

thanks just order a set :agree::agree: :agree:

Seriously, why waste your money fitting a set? they break up at high rpm, I & other members have ran without them for years with no probs.

None of my race and road cars had them, none of our cup cars race with them......never had a problem without them being fitted.
