Comp. ratio....

I've got a question, I would like to find out my compression just to know what it is and it just kinda bothers me cause I can't seem to figure it out. The engine runs like a top, but I would just like to know. Pics of the engine are in my gallery. It's my 82 bronco and we built up a new 351w for it yanked out the 302.
The winsor was a virgin block, never ran, it was a factory 86 351w from ford from carb to oilpan. When we had it all torn down, we stuck in some flast top pistons and used the stock heads and used the basic head gaskets that came with a felpro master gasket kit. What do you guys think my compression is also what cc are the heads, I think they had eao7 or something on the castings.

thanks.

The only way to know for sure is to have the correct head casting numbers, and your head gasket compressed thickness.
