Will the ls-1 heads fit a 5.3

This is a discussion on Will the ls-1 heads fit a 5.3 within the Internal Engine forums, part of the LSx Technical Help Section category; will this interchange work and does anyone make a 4 barrel intake for those heads?...

    yes, the heads will fit. my only concern is the 2.00 intake valve size versus the 1.89 on the 5.3 heads clearing the cylinder walls. edelbrock makes an intake for the LSx engines.
