5.0V8 marquis GS engine rebuild kits?
 

I am planning on rebuilding my motor and could only find kits from Engine Parts Only based out of Vancouver, Washington. I saw mixed reviews about them, one in particular of badly fitting low quality parts and extremely poor customer service. I was curious if anyone knows of their quality or can suggest any other places to get a good kit?

Thank you. I browsed their site and was impressed. Hope to get the same feeling when I call them soon. First rebuild and hope it keeps her on the road for a long time. This should be a fun project!
