I almost have my motor put together, i have crower 403's , crower valve train, srp pistons, eagle rods, and i have a megan racing header. since i don't have any piping under my car yet, i wanted to know if it was o.k. to break in the rings with just the open header before i can get it into a exhaust shop and get some piping. If not how much piping would i need to make it ok to break it in. i've spent alot of money, and i want to break this thing in right. any help would be great thanks.

 

I'm sure you would be fine running it open header, although its loud and annoying.

 

yea you will be fine for sure....
