Thats a good point and something to think about but first thing first I need to find a head. I thought I had a head gasket problem so I pulled the head and come to find out my intagraded 250 head was cracked so surprise there. S I am tirying to find a good used head and I figured sense it was apart I wanted to see if I could get something to add a little more grunt. After I find a used head I am also going to attempt to build by own intake for it.
