Hey guys I have a problem fresh 318 .040 over kb167 cast rings 302 heads milled .025 smokes like crazy even after abouth hundered miles on it but it only smokes while it is idiling or if stoped at a light. Could this be a valve seal problem? Now I will mention the have been machined for the teflon seals but the place I had bought my parts from said they were out of stock and to use the umbrella seals instead. Let me know what you guys think. Thanks in advance.
