Dwayne also has done all my head work in the past on my Kids s/b 360 and my B/B. Had the same issues with geometry and had Mike at B3 make both systems for the 2 race cars. The 360 was the worst on the iron heads with harland sharp rockers I believe we moved the shaft .450 and extended the push rod .500 . I had to add valve cover extensions for the clearances with M T cast covers. The engine has a different sound and has picked up from 11:50s to 11:30s. in similar air. These guys are the best when it comes to service and advise. Thanks Guys.
