So for you guys that use an Accusump system, how long will it hold pressure? Days, weeks,even months?

Not to get too far off topic, how much compression will 91 octane pump gas stand in an iron block aluminum headed 514 or 521 stroker?

And is there such a thing as heads that flow too much for a street application? Valves too big? Or is it all about camshaft and carb jetting/efi injection curves?
