Re: valve guides
Heating the block helps a bit, Just watch the valve seats don't come loose.

Blah, yeah the head. Not enough sleep last night. :S

Re: valve guides
heat up the head in the oven gently.
i've also heard using liquid nitrogen to cool the guides ready for insertion. Helps get them in easier. |

Re: valve guides
real real question is, is it recomended or necessary to change the guides when changing valves. I am building a new head for the new build. and I plan to get new supertech valves etc.

Re: valve guides
if the head is very high mileage i would do it.

Let the machine shop do it, trust me

Re: valve guides
Lot of machine shops just shim the guides if they're that worn.

I wouldnt touch the guides, they very rarely need replacing
