In my search for a gasket kit to rebuild the 450 I have come across these 2 manufacturers. I have used Athena kits before with success. I have never used any gaskets from Vesrah. I have used their pads in racing but never their gaskets. The Vesrahs are $43 for the whole set. The Athena kit I can only find one or two of and they are $94. Any feedback would be great. Thanks.
