e7's a upgrade?

[billison]

OK I'm going to be doing a head gasket change and a guy locally is selling a set of e7's off a mustang that have only like 20k on them, said 50 bucks will this be a upgrade over my stock 85 cfi heads? and will i have to get special push rods? IF i get then is there anything that does not require a huge amount of money or skill that'll give them a little more kick?

Probly not worth the swap....E7's stock are not that great.

but 50 bucks for a set of almost new heads is not bad, mine have like 150k on them, can't imagine it hurting at all, but if i can get a ok power upgrade for cheap i'm gonna, i'm just tring to get some ideas of stuff to do while i have the heads off that'll not cost alot

Waste of time and effort.
You won`t gain anything over the 85 heads.

85 heads and E7`s are pretty much the same junk.

well i have to change the headgaskets, and i just thought that for 50 bucks almost new heads would be worth it as i'm broke and can't get anything fancy,

I thought you were talking about gaining HP.
If those E7`s have been rebuilt and are in good shape,for $50.00 it`s probably worth it.

Just make sure they`re in good shape though.

i'd like to gain somepower, but i don't have alot of money, but the way i figure a almost new set of heads is worth it, i'm thinking about tring to do a port job , can i put a set of roller rockers on stock heads with a stock cam, or is this just a waist of money?

If you already have to pull the heads and the others are low miles, and you can verify, I would say they are worth it

 

[billison]

Ok, what about this, i used to have a set of 351 heads in my buddies storage, if there still thare, would they give me any power?

E7's are nothing more than E5 heads with a compression bump.

 

[billison]

i think i'll just clean up the ones i have and make sure all is well with them, if i put money into heads i think i'll get something worth while, still would like to know about the 351s

There are different castings for 351 heads so it depends which one your friend has. And yes you can use roller rockers with a stock cam and heads but I would upgrade the valve springs. you can get a set of cobra 1.7s for fairly cheap.
