This is good too, thanks for posting more pics. My heads are off and I'll be doing some minor tweeks here and there to the 'old' engine based on what i see in my 'chamber'. I was thinking of starting a new thread but this one has plenty of good in it already. From what I've seen, just like everything else comparatively, it has burn patterns similar to a SBC. Not that I'm disappointed in the past performance but, who's ok with leaving well-enough alone?
