Hi I run typical 043 (35,5x32) with hemi cuted chambers. They were aprox 53cc per chamber (don't remember the DH correctly) but at the moment with 1mm head down I got aprox 9,08:1 on my 1776ccm engine (acording to 1,26mm DH as I remember). I run W110 and STS (1,1:1) rockers, The valves are STD (not stainless) old shiters from my old engine. I ported the intake and exhaust chanels a little bit. The car runs smooth and sound nice. today is snowing and -7C

(-13C in the night it was) and in the mornig it started frome first go
The car runs constantly 15,201 with no belt and 15,7's with belt.
I runn DellOrto's DRLA 40.
Chemi shape chamber is a pretty oldie

modern chamber shapes seams to be more efficient. But Hemi is a Hemi

its nice to have it
