combo: 526 BBC brodix block/heads. littlefield 1471 HHR (probably 90's vintage). Enderle BIRD catcher hat. k valve. set up by gore. 30%OD. I am at that 30# boost mark I have heard not to exceed with standard BBC block configuration and I need to be a little faster. Question: Would a different hat offer any efficiencies to my combo hat would increase HP without increasing boost? Open to other ideas as well. Thanks ITA!
