BMF cylinder heads have become a well known and very popular cylinder head in the past 5 years. The particular market for these outstanding cylinder heads are sportsman style racing. Up until recently, fully cnc ported heads flowing well over 400cfm was not cost effective for most racers. So what BMF done was to create a market in which every single sportsman racer could have a fully cnc ported cylinder head in and cc range from 310 to the maxx 405 at just about half of what it used to cost to have them hand ported. And at very best, you might only pick up 1-2 10ths. Every body out there knows about head porters and their claim to being the best. With BMF’s exclusive port design and years of real pro stock winning cylinder heads, you can rest assured that you are getting quality repeatable fully cnc ported intakes, exhaust and combustion chambers that make consistent power.
