just buy some brand new prc 220cc 5.3l stage 2.5 cnc ported heads from tsp.. you'll end up with around 10.75:1cr.
they come complete with dual prc springs, titanium retainers, seats and seals.. they're a great budget head. you'll pay quite a bit to get those 241's ported and milled. the flow chart is pleasing on the prc heads as well.
just an idea.. i went this route and the spray loves the higher cr.
