thanks for the info, See I have managed to pull a LS B-18 block that has had the v-tec head on it before.... So you can say at least that part has bee done.... Currently I am looking for a Morroso Oil pain "5 qt" and an oil cooler.... Starting w/ the block first.... My wondering is this I dont know the person that owned or biult the block but I was there when the head came off... How can I tell if it has been resleeved or w/ a Vtec head would it have been resleeved to handle what was on it??? I do know that the there is rods and ARP bolts on it all ready, but not sure about anything else... hit me back and let me know anything about what to look for....
