His suggestion was that we can leave the cam where it is, I can install heads (he wants me to drop to 72cc Eheads that he will go through and change the springs on and get me near 11:1), and cleanup my intake and 750cfm carb (said it looks like my accelerator pump is leaking gas). He said this should raise my compression, add about 50-80 horsepower and he can then time and curve everything for me on his equipment. He personally did not like the #96 heads, he also said that all the Kauffmans he has flow tested have not reached advertised numbers, which is why he is wanting me to go with the Edelbrock. We ended up chatting for several hours while he showed me all of his work, great guy.

He might be a great guy but he is wrong. I ran a bigger cam than you 239/247 @.050 with 8.5:1 compression on a 455 and it ran 12.70. It launched hard. My guess is your ignition timing is way off. Get that straightened out before you spend a bunch of money. Also there is nothing wrong with 96 heads. I guy I know went in the 11,s with them on a street car.
