My order of gasket material for my Gray ports ('82 H30) arrived and it's almost to the top of my project list....

What tips can you offer? Do's and don'ts?

Is the old material a bear to remove...clean the groove really good then seat the new gasket..what adhesive is best...

Thanks again!

Did the same several years ago. Gaskets were reletively easy to remove. As you said, clean the grooves.
Cut the gasket about the same size as the length of the groove, because you will need to stretch it some to install it, and this will minimize waste. Place the "butt joint" in the middle of the top groove and work your around the groove. Use a putty knife to seat it. Did not use any adhesive and haven't any leaks.

Don't recall having any hard time removing the old material nor cleaning the grooves. Once you install the new gaskets, smear a dab of petroleum free grease on them and do not overtighten the dogs. The grease will protect the rubber from drying up and should be reapplied every couple of months. No need to overtighten the ports to get a waterproof seal; if the seal is overcompressed it will loose it's shape and elasticity. The job should take a couple of hours and with adequate maintenance and operation should provide 10+ years of leak free service.

I may add that when cutting the gasket to get it started at the to (as mentioned here by Scott quite correctly), cut the starting point at a 45 degree angle, and end up the same way
I read that Don Case's book, and that is what I did
I just learned about the petroleum free grease: I will try that as I found my gaskets are quite dry!
Thanks for the tip
