I'm rebuilding my Evo and have ordered a heap of parts, including new S&S barrells and Wiseco Forged 10:1 pistons.

My selection of pistons was based purely around compression ratios, which in hindsight was stupid. I didn't want stock CR, and didn't really want to go to 10.5, and on JP cycles they had these Wiseco's at 10:1 which I thought was spot on.

I didn't actually consider the fact they are forged and any potential dramas with forged pistons.

Now I'm reading arguments for and against, and wondering if I've made the wrong choice?

I've read that they generally need to be run loose fit in the cylinder due to expansion, which can lead to wear etc. 

Should I be reconsidering my choice? When it all arrives, will I need to take it to a machine shop with torque plates to ensure its clearanced correctly and won't seize up?

Engine will be otherwise standard, stock heads, EV46 cam
