241's on a 5.3

how much would they have to be milled to keep stock compression? and how much would they have to be milled to get, let's say 10:1?

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.
