Sounds good. I wonder if this is a service that we can get from them or have the manufacturer do it?

I may try to do it myself, all they do is round off the edges of the valve reliefs.

All high performance motors should be what is called in the business "race prepped" this is a de-buring process which will lead to higher sustained HP levels. Please read up here www.sa-motorsports.com/blockdiy/blkdiy.shtm |
