Just got my 6.0 heads in and don't know if I should sell them or try and make them work on my 4.8. I'm not sure if Im better off buying a set of 4.8 or 5.3 heads and having them worked. or having these milled to try and raise the C/R. Any ideas would be great. I have no plans of running a super charger or turbo, just all motor.

 

you would loose way too much compression on a 4.8L dont do it. if i were you, i would keep on saveing up until you can afford a 6.0L short block and that swap the complete motor out.
