the only main key to running an engine in is - dont let it idle on first start up - it can glaze the bore- try keep load on the engine - alot of tuners who run new engines in get a rough tune loaded in before start up- start it and run it on the rollers straight away to keep load on it - and change oil rather quickly - thats about it
