I am planning on a small shot, I really didn't care for it after I frost bit a motor awhile back but I figured just a little bit can't hurt lol. The Victor heads haven't been touched yet and what I'm Gathering from here that it's a much for my motor so I my just clean them up some. I will look into IMM and see what Brian thinks.As far as the girdle I was just nervous about the block breaking so I actually bought that first before the block lol, thanks for your input and experience, you guys already been there and done that so I live the info. Would it be better if I went to a little bigger bore to utilize that has a little better ?
