Which type valve cover gaskets???

[Canyon707]

put a straight edge on your valve covers and make sure there flat. I had a problem with warped covers. Replaced and they work perfect no leaks. I used feltpro gaskets with a coat of white grease but, since I do a lot of valve adjustmet I went to Morsco rubber with steel core so I can remove and replace with no issues.

If your using tin type covers,a ball peen hammer will flatten out the bolt holes if they are a little bent. I am replacing all my gaskets with http://www.superformanceproducts.com/ gaskets.They are very high quality and the owner is a MOPAR guy!!
