I know you guys are probably tired of this topic. I've done the research on the heads and plan on droppin some (L31's) in my 85 chevy truck. I wan't to know if anyone has done this and what problems you might have run into when it came time to put the accesory brakets back on and mount everything. Are the holes the same as an older 350? or different? I will be running a/c.
I appreciate any help.
