Speedpro H405 pistons, what to expect for performance?

A new set of pistons kb 107 is around $200 which I am sure would be cheaper than a bunch of machine shop wwork. Do you all think the Speedpro H405 pistons will be OK for just a street driven car?

ok so have the old pistons pressed off, have the thing re balanced, and then press on new ones... ring gap will change from one piston to the other as well... sounds cheaper...lol

i have speedpro pistons in my slant and race it all the time with no issues...
