Thanks, I have a new set that I've not checked yet for vol. The valve pocket depths seem to be within ....005" of each other. Another project for winter.

Seems to me that products costing quite a lot of money should come ready to go. I sure dont call a 6cc variation ready to go. You'd really think that a company like Edelbrock would have their sh*t together.

Yeh, If you look carefully at the left side valves and compare with the right side valves you'll see that they are at different angles. This is factory design compensation for offsetting the cylinder bores to the left of the crankshaft centerline.
To get equal compression ratios, you also need to cc the area in the block above the piston and in the valve area - needless to say, a tedious exercise.
