hey guys, what happens if I do a 5.3 to 6.0 and install the 862's to the 6.0? the thing is I had them ported, polished and the 3 angle valve job on them and kind of would like to stay with them if they will do me any good.. or should I use the ones the 6.0 have?? cause i dont think I can afford the heads job again right now..
thanks guys!

You will gain a lot of low end torque and lose a lot of top end horse power.

2012 Raptor - 497rwhp at 10psi
If you aint breaking - you aint going fast enough
Alot of people down here swap 5.3 heads to bump up the compression with good results.

will work fine
had a friend with and lq9 6.0 and had an ms3 cam and 862 heads ported, milled, and valve job and went 12.3 with traction issues. so i think it will work good.
WOW! That will work!! It would work better in a Lq9 vs Lq4 right?? I'm talking N/A..

heres a comparison dyno the red ( 402 rwhp) is when i had ported 706 5.3 heads..
the blue line is from a head and cam swap
Simple: 408 on steroids!
single digits coming soon!
It will always "work better" when you run them on an LQ9.
BUT...since the cc is a lot smaller on the 706/862 heads (about 10 cc), you deck them a little...and they are going up against an LQ9's flat top pistons--there might be a concern of PTV. But since this combo has been fashioned before and there have been no major problems, I am sure you'd be fine.
