I measureed my deck clearance on my 351c and I have .030". I am probably gonna freshen the engine next winter so I will deck the block then. As for now I would rather up my compression some other way. Is there a thinner head gasket available for a Cleveland? The thinnest one I found was .041". That makes my quench .071". That sucks!------------------

.030 deck clearance is a bunch and .071 quench/squish is way too much to prevent pre-ignition. But, I duuno about the gasket options you may have. I'd deck the block.  SteveW

I have tried to find thinner gaskets in the hopes of raising my compression a little. But all the gaskets I found that were thinner, had a much larger bore size and actually had a larger cc volume than the Fel-pro. I'm not sure if that would help you any or not. I do remember that they werent cheap either.

So what your saying is that I won't be able to raise my compression, but I may improve my quench.
What gaskets are they?
I'm sure that I'm gonna deck the block next winter. I just don't want to do it now. I've made a lot of changes over this winter and I want to see the effects. Racing season is starting very soon and I still have a lot to do. Can't wait!  ------------------

I'll dig that catalog out later today after work and see if I can find them again.

Well, I looked, and...I was wrong, they are thicker.
They have a bigger bore size and more cc's than the Fel-Pro. So thats a no-go.

clevelandstyle,
I ran across a site sometime back where there are thinner gaskets for 351C. The thing I'm not sure about is whether they're suited to your type of application. I'm not actually sure what environment they're designed to work kin. They're copper gaskets. I've never used them, but you can at least take a look at the specs.URL is:

Although the .021 gasket thickness looks good, it requires that I O-ring the block. I don't think I'm prepared the do that. Thanks anyway.------------------

Not that I would try this, but we had a guy that I race with run copper gaskets (he needed more deck clearance) and he didnt o-ring the block or heads. And he never had any problems with it.
