Quote: are you guys sure it had 5.7 heads on it?? i guess i havent seen "new" 5.7 heads, but the drag pack intake is meant to fit 6.1 heads,,, there are no 5.7 heads on any packages they offer. id think the intake is for 6.1 heads,,, so they used 6.1 heads
The newer 5.7L heads have larger ports then the older version. They are very close to the 6.1L heads and the intake for can swap over.
This is true since 2009 when VCT hit, AKA "5.7 Eagle"
