Skip-couldn't get the link to work.Hit a gateway time out.

Can you cut and paste it??.

Link works for me. Pretty pictures.

Try this. I think it's the same.

But, maybe not.

Got it skip.Actually I bookmarked it.Oh,the one thing it didn't say it it is best to have GM screw in rocker studs installed.You have to be careful which screw in studs you use because with some with push rod guides they jam up.And when swapping to Vortecs you have to use the vortec intake as stated in the link,but you also have to use the shorter push rods too or the proper length to any cut made on the heads.They talk about cutting down the heads,but don't say anything about adjusting the push rod length.And when going for a larger lift,you have to machine the heads for the springs needed and guide clearances.

Very good read overall but no info on V6 heads.
