Brian IMM is on here and I’m surprised he didn’t get back to you. I Dont know him personally but have friends that do and they are very satisfied. The Bloomer heads are the new kid on the block and are a great head developed by two brothers that do fantastic work. They are cnc’d by a well known shop. These heads will easily get you in the 9.’s at the weight I suggested. That’s a head that you could slowly upgrade your engine components and keep going faster. Several posts on that head on this site.
