stock 5.3L heads are 10:9:1 and flow 62cc
if im wrong then someone needs to change the sticky on here...
its a good idea to get these heads ported which i was quoted at 500-700 dollars which if you check websites on ported 5.3 heads....getting these done will save you 100-200 dollars....
i got them for 250 and had planned to put them on with my tr224 cam, but thats just not going to work out....you can check TSP's website for exact flow numbers on ported ones...pretty sure its around 30-40 at the wheels
