Ok heres my dilema. When I bought my twisted wedge heads the guy told me they were non o-ringed. Well I bought fel pro-1011-2 non o-ring gaskets for them. When I went to put my heads on last night the heads had a groove in them. These to me are o ringed. Would my non o ringed gasket work? It has a wire around it so whats the big deal?
For more certainty this post will kick it back to the top - and/or you can contact folks at TWS and FelPro's tech lines on Monday and see what they say.
