How Can You Tell If Its Forged Also How to tell comp ratio???
 

How are you able to tell if you have forged components.


I just thought abotu it and the engine had been bore dover so new pistons had to have bene boguth so i dont know if im runnign hyperheutic ro whatever or forged and before i start building it it would be helpful to know so i dont go BOOM.
Also How would i go about finding my compression ratio wiht thse pistons i was told it was at liek 10:1 but then I have diffrent heads then stock and the comb chamber is actaulyl like 8 cc's bigger thus lowing it a decent amount fi it was 10:1 on a stock motor?

Thanks
