Hi everyone. I need help before I attempt to do this .Iam installing a stock LQ4 out of a 2002 silverado into a 98 crown vic .I need to install a car intake for hood clearance i was gonna use a regular ls6 intake but My buddy has a 2007 6.0 gto he is installing a set of patriot heads and a fast intake on and He said that i can have his heads and intake .Will they work on my LQ4 with out any piston to valve clearance problems and what kind of compression would i see with those heads .Are the LS2 head's chambers smaller than the LQ4 chambers . Thank you for Any info i can get on this subject.
Thanks John

if they are 243 heads, you will pick up a lil bit of compression, and maybe flow a few cfm more.
i would say its not really worth the work.
if you are going to swap heads, but some quality ported ones.
good luck.
