If you are, at least do this: get a set of porting bits and take a die grinder or drill and remove the Thermactor bumps from the exhaust port roofs, if you're getting the heads reworked, also take a header gasket to use as a template and open the walls and port roofs to match the gasket, blending this down into the port. This takes about an hour to do all eight ports and really improves the flow.

Specs are 256/266 advertised duration, .422/.445 lift with 1.6 rockers, 116* LSA. 1.7 rockers increases the lift by .030. Full roller 1.7 rockers netted the 5.0 Cobra engines 15 HP. The stock HO roller is just a step above this one in specs. The Cobra 5.0 cam also works well and similar in specs to these two.
thanks for info. What is a good gasket set for-pro?

Head gasket ? FelPro #9333. I used these on my aluminum headed 331. They sealed for 12 years with all the expansion/contraction you get with aluminum heads on an iron block. I liberally spray them with copper kote before installing them.

You can find them all over the internet, not as cheap perhaps. Especially as you have the engine apart now, i would strongly consider them. E7TE heads are boat anchors, some of the worst castings there were for the small blocks. However, at the end of the day, its your engine and your budget, im just passin along the information.

Look at this way. A stock HO 5.0 makes 225-235 HP with E7 heads & a mild cam with crinkled up stock headers.

Here's my 5.8 build & parts list that I did for right at 3K with me & chapter member turning all the wrenches from crank out & minimal machine work. ( Intake mod not needed for you)

https://www.ford-trucks.com/forums/1...l#post16937337

The 512 Comp cam is listed by them to be the most cam for a stock 5.0/speed density truck & is only mildly more aggressive than my stock 5.8 cam.

What's the back story on this truck? Who did the EFI swap?

Those witness marks on the TC are worrisome.

Got it, missed it before.

You can safely get 300 hp by the stock computer & the GT40 heads aren't going to push you past that.

I see you've never actually run a set of ported E7's. They were actually better than the early 351W heads, right outta the box.

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.
