For the E7TE heads use a standard size SS exhaust valve and the standard size 2.084" stainless intake and size intake bowl accordingly.

Those heads have cast iron guide inserts installed. They wear easily and we never used them excepting to fix a severely damaged guide.
We then install K-line bronze guide liners which wear very well even in severe applications.

Back cut valves and blend sharp edges for some additional grunt.

Do you have the part numbers for valves, valve seats and the valve guides. Also should I replace rockers and pushrods while I’m at it. They seem to be in good condition with no scoring and all shiny metal on wear parts. If so what do you recommend for rocker arms and I’ll go with stock melting pushrods.
E7TE heads have hard exhaust seats OEM.

A set of stainless valves is about $200. We have them on the shelf.

Your machinist should have K-line guide liners. The existing iron guide is reamed and the liners installed.
They are much harder than the iron and wear well.
