ET Performance 5.3L Heads
The heads are cnc ported by ET Performance. The specs are on the web site www.etheads.com under the LS1 4.8/5.3 head section. The only difference is these have 65cc combustion chambers.

The Fast intake is hand port matched for these heads and is 90mm.

The camshaft is a 238/ 240 .605/ .609 112 lobe separation.

Would this package be a smart choice for an LS2(06 GTO)?
