Ok so just wanted to know a couple things.
How big are the chambers on the L92 heads.
Also how much can I mill them down?
What would the compression be with L92 heads and a 4.03 bore with a stock 6.0 stroke and a factory thickness head gaskets?
And lastly how well do you think a set of L92 heads with some port work and a mill and valve job would do with nitrous compared to a set of 243's also with some port work and a mill and valve job?
