I was wondering if I should have my jugs bored and heads milled at slp. Or wil any macine shop be just as good if not better. The reason I am considering SLP is not just because there reputation (so my dad says) but mainly they are only 50 miles away. But I had them quote how much the job would be and it was $40 dollars a jug to be bored to 650 and $45 for head to be milled for that size. In my opinion isn't it the same job at local machine shop with a cheaper price. But let me here yours. Oh ya, when you bore to .60 oversize do you need bigger head gaskets. This is all for an 85 600 by the way.
