4.8 and 5.3 heads,any differences???
I might have a chance to get a set of 5.3 heads.Are they any different than my 4.8 heads??
If they are the same i thought i might get them and have them worked,also lower the compression some so i could crank up the boost some more.If they are different,what are the differences?
Just kickin around some ideas <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

You're not going to be lowering the compression any...maybe .1-.2, but that's tops. Better off getting some 5.7 heads worked to lower the c/r.
