On heads, how do you measure deck thickness. Like AFR says their heads have .75" deck which is great for boost. From the deck (surface that bolts to the block) to what = .75"?
is just the thickness of the slug of Al on the flat side around the combustion chambers of the heads. it aids against lifting the heads
I totally get that, but say you take a x-sectional slice of the head, where does the deck thickness "end" when they quote .75". Doesnt matter anymore to me, this was an old post, but nobody ever answered.
