I know I can call around myself ,but thought I'd give it a shot here anyway.I have an excellent G head that I would really like to use. It is absolutely perfect,no cracks between valves,but it is the dreaded OSJ head. I have the original cam,but it's a N/A.Does any one know if you can get an OSJ cam for a turbo? Is there enough meat to regrind to turbo specs? Could I use this in a 2.5 turbo.I know it's a little longer in duration, but advancing the cam about 2or3 degrees puts it pretty close to turbo cam with a couple of degrees later on the closing side.Any Ideas or comments?
