cumbustion chamber size?

does any one know the cumbustion chamber sizes of the to following heads
d8oe,and e7te. i belive the d8oe have 69cc chambers and the e7te have
64cc chambers my freind in california gave me a set of fully ported and polised heads but the problem is he accedenttly gave my 2 differnt heads
but i called him and he said the heads were the same except for the holes
where the smog hups are on the exaust ports any info would help so id dont
waste my money getting the valve seats cut for bigger valves

heyrazorsstang dont make fun of me for not graduating high school i had to drop out and work full time so i could support myself and pay rent .water pog im sure the one cyl head is a d80e but the holes for the head bolts are 7/16th
not 1/2 so now im confused the other number on the head is 3k19 but that dosent mean any thing it is located in the rocker area .dose any one have the tools or a way i could measure the combustion chambers
