I've got myself a RST lump. I'm having to build it up myself as I bought the head and bottom end seperatly. I'm going to give it a full service, fuel filter, oil/oil fiter ect ect, and new gaskets all round aswell as a head skim, but can the engine be driven straight away or do I need to give it a rolling road tune-up session to make sure the ECU and emissions are in check?
Also, is there anything else I need to door be carefull with befor I can get it can be driven?
