I just heard it is a 110 ICL but have no idea what the LSA is. It is crazy that GM thinks the exhaust port sucks so bad on this head that they need a 20* split. It is starting to look like 228 on a 110 ICL is all that will fit at stock compression height. You are giving up a ton of DCR that way. It makes sense why aftermarket cams have horrible tq numbers and don't really come on till 5K or so. I really wish GM would have given us some intake valve reliefs to work with on this. To maintain stock DRC with a 228/110ICL you need about 12.7 SCR. Scary isn't it.
