Integral Valve Guide (Broken Boss) Repair Options

Wyrmrider said

prh gives the proper fix
couple of things
new guides will not be concentric with the stock ones so bvvc
what kind of shape are the guides in?
do you need new guides anyway?
you could do what the porters do and cut the guides down
and put in inserts if you need guides
does it need ex seats
valves sunk?
magnum heads crack check

lots of conflicting advice you have to sort it out
are these heads worth putting money in for the long term or for long enough to get better heads
if so just clean up and run it

Thank you both for the advice. These heads were purchased to rectify oem cracked heads with an exhaust valve problem and were intended to be a long term solution for a truck that gets driven 6-8k miles a year. An expected upgrade with a lesser financial obligation that EQ Heads prepped by PIE or Hughes.

The heads were fresh from a machine shop, deck looks perfect. A good looking valve job had been done on all valves and they were literally still in the machine shop plastic bags when I purchased them. According to casting numbers these heads started their life as 1.92 intake valve and at some point were machined to a 2.02. Looks like some port work had been done too to smooth things out.

I will probably go ahead and get all 8 bored out with inserts put in as long as its not too costly. I think the guy told me $20 to replace a guide if I were having multiple done and $10 to cut a seat which would be required for any guide that was replaced. A $250ish investment for piece of mind I suppose.
