I have a young friend I work with who is going to have a B18C1 engine built. One of the shops he came across is Precision Head and Machine in San Diego. The address is 7643 University Ave. San Diego, CA. 92115. The owner and builder is John Campos.

Does anyone know about him? Has anyone done business with him? Has anyone had an engine built there? Are there any good or bad things we need to know?
