hey guys, So first off, i have a 7m head that is not being used form a engine in which i threw my rod in. and i am currently taking automotive classes at my school. and with all the machines an stuff i have access to, i've had some crazy ideas for that head. i am thinking about doing a 3 angle valve job, and putting bigger valves like Sheaf. He is the only one i know that has done it. I am also considering shaving the head down for more compression. i heard that this could be a bad thing. the problem i am having is i don;t know who sells oversized vavles. i know trd makes or used to make some stuff for the celica, and i would love for my valves to be trd as well. leave input or whatever like performance increase for whatever i would have. thanx!
