I'd like to know your feed back on the power increase. If people are wondering why Im interested in this, oversized valves allow you to increase the valve seat diameter and then your head will allow more air into the combustion chamber. Basically better breathing.

 

Hello I am actually in the progress of having my car tuned by Speedfactory fabrications in university place, and i have a built head and motor, but I can help you on the head, and I live in Oak Harbor if you ever wanna cruise. But PM me, will talk.
