[Mgs] Project 74.5, valve guide options

[cyberemp at comcast.net]

Greetings 0 list.
Head for 74.5 needs guides. Machinist is offering to put bronze sleeves into 
existing cast iron guides,(after reaming current guides, of course) but I'm 
curious to know if anyone has any experience with this technique.

Back when I rebuilt the engine on my first car, (1967 Cortina GT) the shop 
"gnurled" the guides.
Of course they also rebuilt the short block which threw a con rod through 
the side of the block within a year. Ouch. 
warantee not much good when your speedometer doesn't work. At least that's what 
they claimed.
But wait, I'm yammering bitterly. Blame the pain meds I'm on.
   
$ is a factor, as I'm still on disability, but even though I'm selling the car, 
partly to fund next project. 
I just feel that if your going to do a job, do it right.

machinist is checking valves to see if they're okay.

My second option is looking at Northwest pacific parts flyer I got in mail, 
(sorry Ed ;-)  package deal for valves, guides and springs. (can't find flyer 
right now) I'll send them an email asking what kind of guides. Cast iron or 
 bronze, and the valve material.
  Total package was around $108 if I remember right. That might hint at what 
kind of materials are used.
Apparently valves can be stainless steel, stellite treated and who knows what 
else. 
guides can be cast iron, bronze, possibly others.

I just visited Barneys site. Got some good ideas there.Thanks Barney!
    Any one have experience with the bronze guide inserts? this would save cost 
of buying and r/r of guides.
