The question I was going to ask was what is the final
result on the height of the stock head, but really the
answer I need is calculating compression.
I'm currently having a head ported, polished, seats
stepped etc. And I'm looking to have the shop mill the
base of the head to increase compression.
Does the machinist need to calculate the capacity of
the combustion chambers once they've been CC'd to
figure the ratio and the amount needed to remove from
the base or is it independant of the combustion
chamber smoothing?
I'm actually aiming for a 9.7:1 compression ratio
which R&T did to a '74 1500 by removing .150" from the
head of a low compression engine. But I'm assuming
that since there's material being removed from the
combustion chambers this calculation will be
increased.
Yes, no, maybe so?
