915 j heads cc

[67valiant]

hey guys how do i figure out the cc of my heads, i want to buy upgrade pistons for my 360 but do not know the cc. they are the 915 j heads with no machine work done to them other then a valve job, with the 1.88/1.60, and the deck height is stock nothing has been milled, is there a standard cc for these?
thanks, john

Should be low 70's CC, a cc guage from summit is a wise investment for the future if you choose to measure future heads.

Honestly they could be any where from 64cc to 72cc, I have some that are 69/66cc never milled.
One head had had 3 chambers that were 69cc with one at 64cc

Always cc your heads after head work/valve job has been done.jmo
