AllPro Head Question
AllPro Head Question I got my AllPro heads in the other day and overall there A+ head. One question I had was on the combustion chamber. Im putting these on a LS1 (3.905 bore) but the chambers on these heads measure alittle more than 4 inches. 
Will this work ok or is it going to cause a problem...power lose, detonation, ect. The other problem is with one of the valve guides. On the head where the bronse guide was put in it made a small crack down the guide/Intake runner. He is a picture of it I took with my camera phone sorry its not the best but the arrow shows were its cracked.

If you got them directly from All Pro, just pick up the phone and call Suzie or Bob. Bob is out this week in FL.
I run 6.0 heads, and will be migrating over to All Pro heads in the next couple of weeks. Probably similar to what you have, except I went with Inconel exhaust valves.

yes they will cause a problem the gasket cant hang over into the chamer, i did it on mine and it cause problems with the gasket and leaked.
felpro has mls, also GM has them in a mls 6.0" bore for the 6.0L trucks, id get the Gm ones, they are cheaper and work just as well. hopefully they don thave a wait on them.

Kinda off topic but you happen to have any pics of the buildup and what kinda exhaust setup are you running from the DP back? I'm wanting to get an idea of how much mine's gonna quiet down once I can finally afford to put the turbo on it.

The exhaust is pretty much just 3 inch off the turbo run threw a set of FloPros and dumped in front of the rear axle. I sent my turbos back to trade in for a set of Turbonetics 62-1 turbos with .68 a/r t4 p-trim exhaust housings and v-band. I had t3 housings and thought they might be alittle restrictive and decided on the t4 housing instead.

Ahh, ok. Thought you already had the manifolds and all done....just waiting on the new heads to put the motor back in. Well make sure to take plenty of pics, cause by the time I can afford something I may decide to go with twins if the clearance and all is good.
