I was aware that the E7TE heads were considered much better than the late 70s to mid 80s heads (D8OE etc.) but are they actually as good as, or better than the C9OE heads? They do have the advantage of hardened seats, and pedestal rocker arms.
Well maybe not right outta the box, but Ford did send a set to Jack Roush to have worked and the flowed better than the late 60's GT40 race heads. They used these as a template for designing the new iron GT40 heads.(late 80's) I've run a set of home ported E7's and they worked just as well as the GT40 heads I have on my 96 E150 van. Never dynoed them on the roller 5.0 they were on but with a B303 cam and 1.7 rockers, they pulled up to around 6500. They're hardly "boat anchors"
Now are you comparing ported E7's to ported GT40's? Or are you comparing ported E7's to stock GT40's? Comparing a ported head to a non ported one is like comparing apples to oranges. If a person is on a budget porting the stock heads is the way to go. But if there is a little more budget starting with a better pair of heads is the way to go. You will always see bigger gains starting with better heads. I'm doing it both ways. I'm porting my stock heads on my 96 351W and I'm porting a set of GT40's for my 89 351W. No matter what heads you are using they can always be improved with some porting.
It's usually easier to paint the parts when they're apart, as you can get at them from all angles for a more thorough coverage. Have them paint the block before installing new brass freeze plugs, so they really stand out, if you care about this little detail.
When I had my heads rebuilt, I also had them remove the AIR bumps, but the tech who did it took so long that they charged so much for that little mod that even the head machinist said I probably could have gotten better aftermarket heads. And I ended up with stock heads that just had the bumps removed. So it depends on who does the work.
I’ll see happens with the block and crank if can use my pistons it frees up some $$
And thanks my same thoughts but never took the time to paint an engine
Did all the parts separate with lots of cardboard, blue tape & plugs.
Block was on the stand.
All those "all over" paint jobs on the tee-vee shows drive me nuts.
Things need to come apart from time-to-time & big chunks of paint breaking off bolt heads & mating surfaces, seams, etc. get everywhere & in everything.
This pic is actually from before my build with just some clean up & detailing. I never had a full dress pic after the rebuild till it was back in.
