Banged the old guides out, wasn't a problem. I have the new guides in the freezer and the head is sitting in the sun under a black shirt, might warm it up a bit. Worried about baking the head with the rubber intake manifolds still on the head.
Thanks again for the help.

Why are the intakes still on the head? Putting the head under a shirt in the sun isn't going to heat it at all. Remove the intakes and do it right the first time before it costs you more in the end. You should replace the intake boots while you're at it incase of any leaks or cracked or dried out boots.

This is a one day project. Intake manifolds are on the head because they don't leak now and I'm going to upset the apple cart by removing them. The sun is going to warm the head up, not 450 degrees but around 150. Every little bit helps.
Have you ever replaced your guides?

Propane torch worked good.
Honing the guides so the valves would fit has been the most time consuming part of the process.

As for removing guides; as someone stated, blast the noses so there is absolutly no carbon on them. If the guide is iron, heat the head and drive them out. If guides are bronze, or oem Z1 brass, don't heat the head.
We install all guides cold and in a press with special fixtures. We never pound on a new guide.
A sunnen guide hone finishes it up, ready for the Serdi.
