No special tools needed. Small flat screwdriver gets the connector tubes out, and the short intake bolt and a pry bar gets the injectors out.

 

so i take it the intake bolt skrews into the top of the injector??

 

Great, Thanks

2001smoker, You have it right

 

hmm so i guess its pretty simple to do them. the back two look pretty tough

 

Any one had their injectors cleaned and pop set? Whats a fair price for this? first place I called (Central Motive power in Denver) wants $60 per for this service and I have a couple of offers for a full set of low mileage 275's for less than $250.
I'll make a few more calls tomorrow to see if I can find a better price
