Default question about a cast manifold I just bought....

http://cgi.ebay.com/ebaymotors...ZWDVW

Just bought one of those manifolds for a budget build and noticed the 38mm wastegate hole is a little smaller then the actual wastegate.

Will this effect boost creep?
Should I go to a machine shop and get it bored out a little bit?

Thanks for any help

i made 330/260 on that mani, used a 35mm to make 300/255 and had NO boost creep or spiking issues.

Only issue i had with the mani is the wg will hit the head (for vtec heads, ok for non vtec) and the gap between the #2 & #3 runners is so small theres barely any room for the dip stick
