I'm going to ask my Heads question here

[ManiacLS1]

I'm installing a set of heads/cam in my Firehawk this winter. My old LS1 heads are going to be sitting around collecting dust afterwards. Can I get a performance boost from installing these LS1 heads on my 5.3?

Nope, no gain there. Youll actually lose some compression and power. Most of the LS1 guys want p&p 5.3 heads.

You could always get them milled a bit!! Not sure what the max is before you gotta start milling the intake too.
