Compression question
Motor originally had 9.2:1 cast pistons in it with regular 350 iron heads on it, but now has Trick Flow 23* 62cc aluminum heads on it. . .
. . is there anyway to figure out the new compression?

Do you know what size chambers you had with the 350 cast heads? Once you figure out the new static, subtract 1 point since they're aluminum and that's a rough mark of where your at.
Example, my block is fitted with 12:1 slugs based off 64cc heads. My AFR's ended up being 69cc so it took it down to 11.3
