If I install 6.0 .heads on my 5.3, do I oder bolts for the 6.0 or 5.3, or are they the same? I know it may seem like a dumb question but its something I didn't know so I figured I would ask.

6.0 heads on a 5.3 is a bad decision but if your going to go thru with it, then get the bolts that match that year block you have

the cc of the 6.0 heads will drop you quite a bit...but who says you need low compression to be boosted...
I guess that is the old school way of thinking.
I think if your going for super high hp lower is better. But it'll be a turd outa boost. There's alot to read on this. I did a ton and I stayed around 10.6:1 for my setup
Well I'm getting Allen to do the actual turbo build, I just want to knock some things out while I'm waiting to recover from moving and the holidays. Of course I'll go by what he says, I haven't actually asked him about the heads and CR, I know he is a busy guy and I try no to bug him too much. It's not like I'm taking it down there next week. Shooting for 650-700 at the wheels.
Wouldn't it depend on what 6.0 heads he's going to use? 243's came on a 6.0l (LS2)
True, but either would drop compression.Quote:

317s on a 5.3 net you 8.4 cr extremely low,
your better off with 9.0-9.5 for most builds
The 317's are the only ones I have looked at so far. I would be interested to know what you would suggest though.
Leave your heads you have now.
Both my 53s have 243s on them. One came with them from factory
Thanks Quik
