I'll wait untill I get ready to build another engine before I look in to ordering a head. I see now that I mis read Daves post and the heads are now available only in .6.5 compression. Thats better and should be more user friendly than the 7.0 The increase in horsepower is impressive. If I can feel a nearly seven horse increase with a C or F3 head, you bet I could feel a 13 horse increase over the BF 5.9s
