That's why I asked about a raised cam block, BES does stuff like that also. APD does alot of testing on all kind of stuff, they had a real good article a couple of years ago on some Big Chief testing that they did. I don't think APD gets as much credit as they should.
Actually do not need a raised cam block. Mine is a 4.5 stroke in a 9.8 deck also.
That article was the start of a major change in cam profiles, the engine was a good friend of mine, he purchased from a big name builder and put a terminator on it. It developed the mystery "alky miss" and did not run nearly as well as it should of. APD was close so John Kyle did a bunch of work and figured it out with a cam he designed. They also have designed some of the best bbc heads on the market.
