Stopped my sbc valve cover leaks
I would of given this product 5 stars but based on the non factory looking packaging the gaskets came in which was a taped piece of cardboard box folded over them(the packaging, not the actual shipping box)I was skeptical of keeping them thinking they had been used & returned. After contacting speedway about the issue & them stating that's normal I said screw it.
I've read other peoples reviews for these same gaskets that say that these did not work for them. However I did notice on a couple of those reviews those people said they had nice cast valve covers. I have cheaper stamped valve covers, coupled with longer bolt load spreaders & they sealed perfectly on my 350. It Could be a matter of cast vs stamped covers that decides whether these will work for you or not.
