FE Head swap
Hey y'all. I've got a '75 390 that is in desperate need of more compression. I have a set of heads off of a '67 352 that came out of a camper special. I didn't know if there would be any compression gains over the stock '75 heads. I would imagine there would be since the 352 that i have is a pre emissions motor. This build is a budget build and I'm trying not to spend much on the heads other than sending them to be milled and reworked at a machine shop. Any info y'all have would be greatly appreciated! Thanks!

This chart seems to have some errors, but it shows combustion chambers in the era of the 352 to be in the area of 68 to 71 cc's. (roughly)
http://www.fastfairlane.com/Engines/feheadid.html
I can't pin down the CC size for D2TE heads, which your '75 390 might have. They are reported to have chambers similar to above, to as high as 74.
As OEM, your heads would have hardened valve seats. The 352 heads would not. Unless someone reworked the 352 heads, they probably need some tlc--valve job and seals at a minimum. That, combined with all the joy a head swap brings, in the face of no real compression advantage, makes this a questionable swap. If they need more than that, you will be astonished at the cost if you are not already.
As OEM, your pickup 390 used the 410 spec piston with a compression height of 1.66" (approx.). That leaves the piston .100"+ down the hole. The solution is 390 car spec pistons with a compression height of 1.77"+/-.

guys thank y'all for the info but i have done some more looking at the heads i have from the 352 and they are shot... it looks like someone left them out in the rain for a while and tried to clean them up. i'm just going to keep my eye out for a nice set of older car heads or something.

D2's are 68-71 cc. That's the smallest chambers aside from the earliest FE heads (58-62 or thereabouts)

You could mill the heads to gain a little, but the gains wouldn't even be noticeable.
Either get new pistons or run 352/360 rods - pistons are the better option.
