    i bought some 241s for my 5.3...

    i bought some worked over 241s for my 5.3 and i need to know what my CR will be since there CC are bigger than the 5.3 truck heads. would you suggest putting them on or take them to the machine shop and get milled down to bump my CR back up.?

    I think they'll drop your c.r. to around 8.5 or so. You'd have to have them milled a good bit to get your compression back up
