some good head

 

One of the valve jobs has more angles or degrees cut into the valve seat. Stock these cars came with a 3 angle job. The extra angled cuts are suppose to promote more air flow over the seat but can provide less sealing area for the valve. They even have a valve job that is suppose to have something like a infinite amount of angles. I would just go for the three angle job and have the valves lapped to their individual seats. If you want more performance raise the compression NA motor and/or port the head.

 

thanks! just trying to get more speed for 1/4

 

if your ports are stock you wont see much improvement if any.. ive done it on a honda crf 450 and dynoed it before and after and that was the only change.. only went up like 3/4 of a hp

 

yeah after the head done , i'll be working on getting an custom intake.it should feel good when i spray that 150 shot nos
