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

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.
