Question... can i bolt an LS1 intake manifold to my 5.3L heads or do I need to run 241 heads? I know the LS6 and LS1 intake/heads are swappable but not sure about the 5.3L

I hear the L33 5.3L has heads similar to the 243..

Also I searched and found a link to a set of headers on summit that will fit an OBS truck for an LS1. will they also work with a 5.3L? not sure if the exhaust ports that they bolt up to are different sized on the LS1 vs the 5.3L

Thanks for the help!!
