never really had this question answered so im asking again
are the rocker arms and lifters on the non conventional headed engines (like big chief and big duke) just as reliable as conventional headed engines in terms of having more longevity. I read somwhere that the lifters and rockers wouldnt last very long in a marine continuous running situation and that some marine engine builders wont build an engine for marine use with anything other than conventional heads. Whats the real deal?
