E7TE or C80E Which heads are better?
I have a pair of both and I am planning on using which ever has a better combustion chamber and lowest CC's. They are going to be used on a 79 351W in my 69 bronco.

I figured that they were better, any idea what they flow intake\exhaust? I believe they are 63 cc's compared to the 69 cc's I have now, do you have an Idea of what this could be in hp increase? I guess 25 maybe....

There's no significant difference in airflow, between the two heads in question. I think the E7's will be a better choice, for the resulting static compression, and also the fact that the E7's already have the hardened seats.

Yup I would run the E7's as well, plus they are set up for pedestal (sp) mount rockers.
You could get some full roller rocker that would bolt right on, just need to check the push rod length......
Port the exhaust and run-um
Real happy with my E7's made some good numbers on the dyno for what it is.....

That 9.6 was with out having all the info. I used the same engine I just used 64cc heads and then 53cc heads just to see the difference....If my memory is still working I think the heads that came on your 79 351 were like 69cc if so going to 64 should not be a problem....

Theres a lot of crap being spread here. First of all, the C8OE heads came with 2 different chambers, 63cc and 53cc, there is a DRASTIC difference between the two. The 53cc heads have 4v cast into them and they are pretty rare, I doubt you have them. The E7 heads DO NOT have 65cc chambers, they have around 60-64 at the highest, not to mention that the E7's flow better on the exhaust side then the C8's do because the port has a far smaller Thermactor bump in a better location. D0OE 302 heads have a 58cc chambers not 53cc, the only head to have 53cc was the C8 4v heads, not even the 289hp's had 53's they had 54's. D0OE 351w heads are 60cc's. You would be better off with the E7's and you would have around a 9.5:1 ratio on a 351, remember to drill out the head bolt holes to 1/2", or get a set of 351 E7's.

I don't think it's a matter of crap, I think there's confusion. The 351w in 69 and 70 had pretty good heads, and they had casting numbers C9 and D0. The typical 302 engine from 68 had an ordinary head with open chambers and smallish ports, casting numbers were C8xx. There was a 4bbl head from 68, but it's rare; smaller chambers and bigger valves.
The E7 is a truck head and another open-chamber design. As mentioned, hardened seats in that head. Nothing special, but I'd use that one. I have some E6 heads that I think would be perfect on a 351; bigger chambers but a closed chamber design; good quench/squish and a reasonable compression ratio.

I don’t think a few cc’s off is crap! The D0OE heads that I personally cc’ed came to 54 to 53 + or - and after I had the machine shop install the valves at the proper height they came out a lot closer. I ended up with 54.5 or something like that I think, can’t remember it’s been a while since I did them. The E7’s I did with the 1.94 1.60 valves were 63cc’s but I think the bigger valves eat some up and no chamber work was done. The D0OE 351 heads I did came up to 62 or 3 cc’s after un-shrouding the valves and a quick polish to the chambers, again bigger valves installed.
Add a 5 to the begining 53.3 53.4 54.2 54.2
I only speak what I have seen my self or have done, if not Ill post a link. I am in no way an internet gear head repeating what I have read somewhere, I’ve been getting my hands bitch up for 26 years mostly on small block fords…….
