    capt is right, cam will change alot of things, it is best to have an end goal first before changing cams.

I might of asked the wrong question just trying to get some advise on performance upgrades for this type of engine ...i have also read those 193 heads arent so good and should be replaced with aluminum heads instead..any opinions??
