Review on Honda B-Series/H-Series Engine Cam Seal - Part Number 658-05-0200 by Jason Rogness

I had previously purchased a cylinder block gasket and it kept leaking. The o-rings were smaller and just didn't work. So I tried the Skunk2 model. Of course this is a much better seal, just looking at the o-rings you can see they are much thicker and therefore fit snugly on the head. I didn't use sealant (like Hondabond) at all when installing and it doesn't leak. Don't worry about other seals, just buy them and fix the leak at the first time.
