Im not sure I understand your question?
I’d think spending under $1,500 on the parts and then having a machine shop do the install for $500-600 for a grand total of around $2,000 is better then having Buschur do it for $1,100 more plus the cost of shipping which on a head id assume would be over $100 each way.
I dont ever mind spending money, but I cant stand waisting it.
