UL heads with K chambers

..

panic are these the vt-cycle ones ? by leaving the heads blank, where the pop up goes ,does it make it easier for people wishing to install different compression hieght pistons or stroking their engine to cut the exact depth of 'pop up' they need to get the squish right. jib

..

cheers panic, thats what i thought . but two heads are often better than one, (no pun intended)

are you saying they have used the iron head fin pattern ,if so that corresponds to the vt-cycles one as well

So they say - maybe it was the only mold they had available? Certainly can't be a patent/copyright problem.
