I like stock E7 heads.
I have E7s on all three of my Windsors.
By choice.
And the goofiest statement of the year award goes to............... [emoji38]

If the intake/elbow has accommodations for EGR, you can install a block-off plate. I made one from the flange off my EGR valve by filling the holes with JB-Weld, smoothing it down, and painting it. It's not perfect, but was basically free.

The "E" cam will be pushing it on the valve springs for either head as that cam has .498 lift and those springs max out or go into bind at around .500 lift so not much room for any play there. If at all possible you would be $$ ahead to change out the springs while you had the heads off and maybe toss a new set of seals on em when you do that for good measure, cheap insurance... That being said.. the '94 I had did have a set of the GTP40 heads with stock springs and an "E" cam on it. That's the way it was when I got it. There also was a lot of clatter in the valve train, I think whoever put it together left it with a lot of slack in it because it still had the stock valve springs in it as well. It did have a lopey idle to it and only 12-14 inches of vacuum. You never mentioned if you had a stick or an automatic, if you have a stick that's ok, if you have an automatic, it'll probably need a looser converter. And also it'll like a lil deeper rear gear as well, 3.73's work really well with it keeping the engine closer to the power band for that cam.. You can chance it with the stock springs if you wanna but as close as that tolerance is you do risk bending a pushrod..

Oh yeh, be time and money ahead to go on and have the heads worked up before you put em on, that way you've got em right when you install em. And they'll already have everything needed when you put the cam in instead of having to tear it all down again when you install the cam...
Ok sweet ! So just checking I can run diffrent valve springs with my stock cam ? And what valve springs would you recommend?
Yes, you can run different valve springs with your stock cam.
I'd recommend something like the TFS 2500100 Kit. It comes with everything you need: springs, intake and exhaust specific retainers, keepers, and shims if you need to shim the springs to achieve installed height. They include an installed height tool so you get them installed correctly.
I have the TFS 2500100 Kit on my iron heads with the stock cam and 1.7 rockers. It is a drop in kit, no cylinder head machining required for the springs.
If you want to support a smaller business I'd recommend Alex's Parts valve springs. They offer an array of complete drop in kits too, from valve springs meant to be stock replacement to valve springs that can handle over .600 lift.
