346 head chamber volume

[71chargerse]

i am trying to determine the ccs of my heads, they are 346s that have been milled 55 thou. i think they were originally 88 or 90 cc. does any one know how to figure what they might be now?
thanks, brent

Nope! not without cc'ing 'em to be accurate. But you could "in-accurately" go with a 2.4 cc's per .010" of milling and subtract that from whatever you think you were at. 5.5 x 2.4cc's equals around roughly 12-13cc's less than where-ever you were before the milling. Not try'ing to confuse the issue, seriously I hope it helps.
