milling heads
I have a '04 silverado VHO with a LQ9 6.0, The stock 317 heads are 72cc giving it a 10:1 compression ratio, I have to pull the heads off to get broken header bolts out, So while there off Does anyone know how much I can have milled off the heads without causing valve clearence issues?
The truck has a TSP 233/239 .598/.603 lift
TIA James
