Just a suggestion,
Don't use gaskets with a motor plate. Use silicone rtv, and tighten it as tight as you like. Using gaskets, you can only tighten the plate up so tight before the gaskets get pushed out. Chassis flex will get them one day too. Actually I o-ring the plate to the block - solves all the problems. Looking at the picture , the o-ring depth looks pretty deep.
it's ok to butt heads, just don't do it with a butthead

The depth of the groove is based on the section of the o-ring. I'd suspect that they are using a pretty thick section on the o-ring to keep the thing strong enough to not get torn while stuff is moving around.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

I o-ringed the AR376 SB plate. If you look close you can see that I o-ringed the timing cover also. It is an expensive process for billet parts. I'm not sure how the OEM's make the o-ring parts in production. They must have some special tooling to keep the cost down.

I o-ring anything that I can because its just so clean and does a great job of sealing. No mess to clean up when taking apart! I have yet to have anything leak that I have o-ringed as long as the o-rings are fresh (replaced the o-rings on the valve covers after about 12 years - they were due). There are several configurations of o-ring grooves. The one I use is quite simple but has served me well. The groove dimension is straight out of the Parker o-ring manual. The one negative on this type of groove is the o-ring is loose and you have to use a dab of grease to keep from falling out during installation. With my new cnc I am tempted to experiment with different types of grooves. Might on future projects.

The charts shown are correct for o rings and quad rings. O ring “dash” numbers are equivalent between the two. Back up rings also follow this numbering system. The dash number indicates size. The prefix to the dash number determines material and form. A great resource for o rings is McMaster Carr. You can find size, material, form on thier site, and the price for a typical bag of 50 rings is usually in the $7.00 range. Sorry if this derails the topic, but I thought it could be of use.

After the machining process o-rings are a lot cheeper than gaskets .

Andy - thank you very much! I had not seen that solution before and its looks great! I plan on getting one to try.
