im about to send my ls block to be sleeved by golden eagle, the shop quoted me at 1300 for 84mm sleeves and align boring the mains.... i have a set of gsr mains and girdle but the guy said he never heard of gsr girdle on an ls block? my question is should i use my main caps with the girdle or isnt it easier to just bolt up the gsr main caps since they came with the girdle?? and does any one know if darton sleeves would be around the same or more? are the golden eagle sleeves good enough for running 25-30lbs? bored at 84mm
