My experience is similar to M. Henry. If you're using the chrome pentroof covers, make sure you use the speaders on the bolts. The covers we seem to be getting are a lot thinner than the OEM's and don't spread the load evenly around the perimeter of the cover. Mine leaked like crazy and there was nothing I could do to seal them up. Massive puddles on the floor after a run.

Finally went with the cast Shelby covers (or any other cast flat edged cover will work as well) and RTV'd the felpro Cork rubber impregnated gaskets to them, let them sit overnight and then bolted them up. Made sure to put a little RTV on the gaps between the head and intake. Not one drop since and my garage floor is clean. Perfect!
