Hey I got the cylinder heads out of my car and the head gaskets were blown. I was told I need to send them to a machine shop to have them resurfaced and pressure checked. Do I NEED to do this or do I have any other options? Is there any way to look at them and determine if they do need to be sent out or not? Also, it will cost 120 dollars for this. Can I get aftermarket heads for a 3.8 for close to this or what other options are there? Thanks
