Integral Valve Guide (Broken Boss) Repair Options
Purchased some R/T heads and noticed when I got home and looked them over a few broken guide bosses in the intake ports. (3 out of the 8). Took them by one cylinder head shop and the owner said they would probably be ok just cleaning up the edges of the broken guide to avoid chipping but suggested liners as well.
Another shop said at least those 3 (and preferably all 8) intake valve guides need to be drilled out and False Guides put in.
Both shops agreed new seats would need to be machined if liners were placed.
Another said it should be fine as is.
I don't want any unnecessary expense but more so want a reliable head and will pay for the proper warranted repair, whatever that might be.
I am fairly new to this and don’t want the machine shops to notice and take advantage of it!
The seller has been solid, accommodating, and helping me anyway they can to get the heads right and on the truck.
Thanks for any advice!
