      These ultra-seal gaskets fit perfect. The silicone bead around each port is nice and provides a nice layer of security. I would however add an additional bead around your water ports because you can never be too careful with that.

      I installed a set of 210 procomp heads. The ports on the heads are much larger than stock. The gaskets are a perfect fit and work great. Bought them on AutoPartsWAY and saved a bundle over the local speed shops.
