Domed pistons with 5.3 heads? Does anyone have experience running domed pistons with 5.3 heads? I have a pair of 5.3 stage 3 heads that have been milled .030" and some 12cc domed pistons. I am considering having my machine shop mill the domes to approximately 6cc to bring the compression back down to 12.5:1. Are there any clearance issues that I should be aware of with this combo?

The valve reliefs are adequate. I'm concerned about piston dome to combustion chamber interference with .030" milled 5.3 heads. I believe the piston domes were designed for stock 5.7 chambers. Is there enough of a difference to create problems?
. i know for Jasons new setup he's running 5.3's milled and 9.10 effective domes and a big *** cam to boot. my setup is 5.7 heads milled .020 and 6.6 effective domes.

Still looking for anyone who has experience with this combo. I'm curious to know if the domes will require massaging to fit with milled 5.3 heads.
