Wiseco is what I have 106 in and 109 ex degree .... Has 70 thou clearance 15 degree btdc intake cam from dot head ex has 90 thou clearance but had to use bandit cam lower profile... ive tried running tighter clearance but for drag racing if u miss a shift booooooooooom in my case If I was to do over I would mill deeper pockets in piston for the valves or if u want to go cheaper double up cylinder base gasket everthing ive read on the net is the dot head and cams will bolt straight on a bandit with 1216 pistons I just did not like the clearances
