think these will make some compression

what pistons?

And sadly high compression pistons don't add all that much power.

We have actually seen quite an improvment in a stock integra b18a1 from switching from the stock pr3 to these pistons.. the last one we did we installed the beast cams at the same time so we are doing just the pistons for now and then the cams later to see which one really helped the most..

What's your target compression with those bad boys? 11:1?

We figured out that it should be around 10.7:1 to 11.0:1 somewhere in there its still an improvment the domes look to be about .125 high
