I just finished putting an AAZ head on my 1.6td, you can see my build (sort of) here http://vwdiesel.net/phpBB/viewtopic.php?t=16482&start=120I really want to get it started but i dont have the downpipe done i want to make or exhaust finished...If i just let it idle up to temp would it be ok to run the little stock downpipe/exhaust? I don't want to ruin my brand new head or put it through any unnecessary restrictions.My brain tells me i shouldn't even be asking this, of course it will be fine, but my wallet tells me ask the fellas first.
