Should be towards the top end, depending on cam of course. I think that's what this 224/228 wants is more head.

Eh.. who doesn’t

Don't we all?

Mine is 5.3 with BTR stage 2 truck cam (210/223), those heads milled .010. Wasn't originally doing heads but the seats were pitted on my stockers. I wish I had gotten a higher lift cam but oh well. This will be paired with a Circle D 2600-2800 convertor and rebuilt 4L60.

Weirdos ?

That should run well especially compared to stock. Haven't seen that cam used much I think 99.8% of people with 5.3s just stick to the 212/218. If you aren't running dual springs I definitely wouldn't want more lift.

I bought ls6 springs for that cam. I would've upgraded those had I changed the cam. This will be my commuter vehicle now. I drive 100 miles round trip to work, every day. When I originally ordered the cam, I was more concerned with longevity than maxing out the power. Then the heads came in to play. I think it'll suit my needs. I'm keeping manifolds and everything. Want it to sound pretty much stock. I can always change it if I get a wild hair.

I didn't notice how slow it was until I got the yukon. Its night and day. Hoping to get a little closer to that.

I would like to switch back to manifolds, but with a turbo on them lol. Quiet is very nice especially on a 100mile round trip everyday! I'm curious to see how MPG comes into play.

my mpg went up by like 5

Switching to manifolds?? .05??

I’m curious as well. Be nice to be in the 19-20 range but that’s probably wishful thinking. With DOD turned off, it was getting around 16-16.5 before. I’m excited to see your thoughts on the heads. Main thing is the valve stem height being the same
