I was reading an article about raising the compression ratio on a N/A 1600 CVH, and it said:

"Use 1300 Mahle pistons, which have a higher crown and therefore raise the compression ratio to 10.2:1 without head modifications".

This sounds good since standard compression is something like 9.5:1, is it true?
Anything else i should know about doing this?
Has anyone on here actually done this?



Cheers people
