302 heads HELP PLEASE!!!!!

First i want to say hello to everyone and glad to be here. I have a question that no one seems to be able to answer for me and i hope you guys can. I have a 302 out of a 1984 E-150 that had a 2 barrel carb. I want to put this motor in my 1993 F-150. The 1984 motor has dished pistons in it. Not sure on the dish size. As far as i can tell they are either .030 or .140. I have a set of E7TE heads that i want to put on this motor and run my fuel inject from my F-150. The motor that the E7TE heads came off of had flattop pistons in it that were stock. From what i can figure the E7TE heads had a combustion chamber size of 60.5 to 64cc's. My question is i can't find any info on the heads i took off of the 1984 carb'ed motor and with the dished pistons in it i am afraid that if i put the E7TE heads on it and the chambers are bigger that my compression ratio will suck. The casting number on the 1984 smog heads are 4E24 and that is the only number on them. They have the smog tube that goes on the back of them and the E7TE heads that i have don't have this. Another reason i want to use the E7TE heads.. PLEASE can someone tell me wheter or not i can run the E7TE heads and what the difference is in the combustion chamber's of the 2 heads. Thanks Guys.

i beleive this will help your compression on your 84 motor. the stock 84 heads are around 69 ccs. if your still in doubt take them to a machine shop and see if they can cc one of each head. if the 84s are 69 and the 87s are 62 you will raise compression by approx 1 point, so if the 84 is 8-1 it would be around 9-1 with the 87 heads.
