talking with mechanic?

[scruffboy]

O.K., I'm out of denial. I have a BHG. The mechanic I use quoted me between 600 -800 dollars. That sounds a little on the low side. I want this done right. I would like the surfaces cleaned well and all that. I've had this guy do work for me before and he was nice, let me in the shop and all. l woul like him to tear it down to the gasket and let me inspect it. How do I approach him with stuff like that? I'd also like to maybe pick the gasket and studs myself. I know this will raise the price. Please don't tell me to do this job myself. I changed my valve cover gaskets and found that challenging. I understand how the things work, I'm just not real good with tools. Any input is welcome. Thanks.
