My understanding is that the squish band is there to get as close as possible to the flat "deck" areas of the combustion chamber to allow heat transfer from the piston to help battle detonation. The kjet heads are missing that flat area compared to the djet 3.5 heads if I remember correctly? The djet US motors had the piston down in the bore to lower compression that leads to detonation I think.

I have picked up a set of 3.8 euro cams, I believe they say k70 and 71 on them. Have you ever looked at these? I'm looking for high end power and the 92mm bore 3.8 redlines at 6700rpm so I figure the cam timing has to be different than all the others. My 4.5 really falls on it's face after 6000. Not sure if it's Valve float starting or just the cams being setup for low end power with the terrible auto. I'm not even 100% sure its got stock us kjet cams actually. But it just stops revving. Drifting it in third is tough so I really was giving it to it in second.
