DVAP is in Mesa... I wouldn't buy engine parts from them again. I ordered a cyl head for a '78 Ford granada 200.. they sent me 1- cracked, sent me another- cracked only the second time I didn't find the crack until the machine shop found it and was going to put in the bronze seats. that time they told me to send it back ( my cost ) and they would refund. because they couldn't help me anymore.. I did that, and there pretty good to deal with... I ended up paying $35 for a cylinder head from a U pull it junkyard and, it was not cracked
