measuring combustion chamber on the head Is it possible to do with the heads attached to the shortblock?
I'm trying to calculate my SCR and I cant remember what the exact cc of the heads is.
They are LS6 castings that I am guessing are milled about .035. That should leave them right around 60cc correct?

well its not a life/death situation
if the heads are 60cc, my SCR is exactly 11.5:1
I am trying to get away with as much as I can since I have a pretty big cam. I wouldnt mind being near 11.8 or so. I'd change the head gasket but the heads are already on the block.

what info are you putting in there?
as in bore, deck height, piston volum etc?
(just curious mainly, but searching for milled specs of ls6 heads might help)

4.03 bore
4 stroke
.054 headgasket
4.1 bore headgasket
-9cc piston
-.005 deck height

I've always used that calculator kumar
-9cc is a domed piston over there.
enter it as 9cc and its 11.55 fo rme
with a 58cc chamber you get 11.82

ya i was entering the piston as -9 like other calcualtors
but its all just a guess
if the heads are actually 62cc, then i am at 11.3:1 which isnt a big deal but might be leaving a couple hp on the table
