Valve spring compressor?

that tools will work 2 values at one time,heads on or off
you may like to look at "Tim's Tool" it only compress one at a time, which I do not think would make very much differance. I used "Tim's " last week on my double springs with .670 lift and was happy
just my .02' Johnny
