What would you do different with this build? I haven't been keeping up with new mods for the last year or two, but this is what I was planning to build for the past couple of years, but wanted to get some opinions in case anything newer/better has been found. Current mods are in sig. I have a set of Patriot LS6 243 heads with stock valve size and stock combustion chambers ready to go on. My planned additions are:
MS3 cam
LS2 timing chain
.040" head gaskets
TSP ported LS6 oil pump
New fuel injectors
My 5-7 year old coated Pacesetter headers are also starting to look a bit rough, so will probably replace those. I was also thinking about getting the heads milled to increase compression. Any thoughts/ideas?

Personally i would have someone spec a custom grind for your setup.. It may be a little more costly but i believe you would benefit overall. Also if you mill the heads you might want to go with a cam that has less lift unless you want to fly cut valve reliefs, or maybe a thicker head gasket. Definitely go with like 36# or 38# and at your stock fuel pressure that will put them around 41-42#.

Patriot heads have already been purchased (about a year and a half ago), so they'll probably need to stick around. I'm okay with flycutting, probably going to pull the engine to do the work. Some things I just realized I didn't add to my sig is I have the Racetronix fuel pump setup and a stage 2 ACE 4L60E.
