I have stock 77 318 heads and can't find what size r the combustion chambers? Also would putting 160 ex and 188 int valves in the heads be a good idea... thanks for reading
 
Most ones that I've checked have been 74-76 cc's.

I'll be right back with the cc's on those heads, but 1st...what casting # are they?

I have some 675's late 60's early/mid 70's heads I can check, which only gives you a ball park, for most r not the same....and of corse they are not 'your' heads.
 
ok.

the bone stock 318 heads I have [off of a canadian '71 dart gt]

chambers = 68cc
while they are smaller round....
they are deep!

you could mill .100 off these things easy, plenty of meat in the deck.
of corse then you'd only have around 47.2cc chambers..lol
