Brad,
Have these heads been cut any ? What size are the chambers ?

I just dropped off a set of LM7 -862 heads off at D&A machine shop last Saturday for valve job and spring swap.
I probably need to stay around 61cc chambers on my 5.3L...but your larger valves make it interesting....

67cc chambers it will drop your comp to around 9 to 1. these heads have stock deck height but shaving decks. 035 max will get you to 9.5 to 1 ( i believe)..get these from me i will throw in the stock bore gen 5 flat tops mounted on the gen 4 rods for around 10.5 to 1 comp. Ive got headers and offroad stainless pipe for truck as well. Ive got a good block too!

Short block is done.
Mild build here...stock LM7 5.3L short block with BTR stage II truck cam (212/218 @ .050", .552" lift)
FiTech induction system, shorty stainless headers.
Just pulled the heads off last Friday to get freshened up and peek inside.
Complete long block came from RetroLS in Cumming...'05 LM7 w/121K
In my '67 Camaro.

I'm thinking the larger valves in your -241 heads might not be worth giving up a half point lower compression in my particular mild application.
