Crazy 408 in the works....Compression Ratio question

They have a huge dish, but appear to only have inline valve reliefs... You'll have to mock them up with your Trick Flows but they should clear.

Tell Ed they have inline reliefs!!
 
Will do Rick!....

Another thing I should mention is the heads have not been decked so far (far as I know of anyway)...stock is 61cc but they were enlarged....basically ported out to a 65cc because of damage in the one chamber. So instead of decking it from making a 61cc to a 58cc now it has to go from the enlarged 65cc down to a 58cc.....could that be too much decking? I forget the general rule of thumb for how much cc you lose per thousandth's of decking. I really would love to have 9:1 CR if possible.
