Finally, my first 360 and goals for it! I'll be asking a lot of questions.

Alright. My plan was to have the heads milled some. After looking around for shops and getting quotes that would cost as much as getting speed pro pistons here in Sweden. Would it be wiser to get the pistons? I've never changed pistons before so I dont know what tools and work it requires. Im not scared to do it, I'm sure I will manage if I do the homework and go slow. Main concern is budget, and will it be worth it considering my goals for this engine as stated in post 1?
The pistons on a 360 have a fixed pin, so they are a little trickier to replace. Watch some YouTube videos on it and you'll get a better idea on what's involved.
