Hey guys, newbie here. been a chevy enthusiast for quite some time now. Seems to be quite a bit of knowledgeable folks here.

I recently acquired a pair of LS2 cylinder heads at the carlisle car show.
I would like to know if they would bolt on to a chevy 4.8L block and intake manifold.

thanks guys

If they are LS2 heads, this engine is a 6.0L with a 4 inch bore. The combustion chambers are designed for a 4 inch bore whereas the 4.8L has a 3.78 inch bore. Also the valves are too large and will hit the edge of the bore on a 4.8L. The heads will physically bolt to a 4.8L block and intake but won't work.
