I just bought a 327 today that i've been wanting for a while. I finally convinced the guy to sell it to me today. I've looked up the casting numbers on the block and heads, but honestly I don't know what i've got. I know the heads are desirable "camel hump" heads, but as far as port volumes and chamber sizes, I've really never compared one set of heads to another. Anybody want to break it down for me? The Casting number follows with details from Mortec.com 3782461....64-66...327......Camel hump,no accessory holes,160/62cc port volumes,62cc chamber
Go to NHRA.com and click on competition then down load chart for the Super Stock Cylinder-head section.
Camel humps used to be desirable. Now they are iron anchors. Any set of decent aluminum SBC heads will out flow them right from the box.
This is true. However, don't forget the nostalgia factor. If you want an old school lookin' 327, the "double hump" heads would drive the look home. Of course, Buick59 is still correct if serious @ss haulin' is the real desired goal.
Not quite a comparison. I'm looking for flow characteristics, smaller port volumes vs. larger ports, Open chamber vs. closed, etc. I'm well aware that I could just toss these in the dumpster and buy some new aluminum heads, but I tend to enjoy building traditional style hot rods with nostalgic parts.

Built this motor with Humps..2.02s..pocket ported..came out just like I remember. The sound..and character is much as I remember my mills from the 60s. A old circle track motor guy did mine. Racing..vortec or aftermerket. But a great strong street motor with a certain feel and sound..Humps for me..
Just a note, if it is a street motor, run flattop pistons. 62cc chambers and domed pistons are not friends of most of today's fule. Can u say "ping, pig, ping"
