Response to Yep,that's it. n/m
The old Gonk from 2006 has the 3.984 crank, but HMM says 3.784 crank.
I also used the older, better flowing Edel heads back then for that Gonk.
Since then those heads kinda got "two-percented" by inflation - they cost 2% more and flow 2% less - every year - for a while.
(You only count the 2% once, that's how the government does inflation it seems).
In any case, the old heads flowed better. Maybe yours are the old ones, before about 2005 or so.
I also used 3550 lb for the car for this Gonk vs 3450 back then, and for some reason a solid cam (same grind) back then, that was a typo maybe.
Should run good either way.
