those 40P's already have stiffer springs and bigger valves. you cant buy a set of 40's at the junk yard and do them up like that for 600 bucks.

i DO wanna know if anyone has used these heads, because when i talked with tristate they wouldnt say who makes the hardware they are using. i'd hate to see someone get their stuff and stick a valve or snap a spring....... but someone needs to step up and be a guinnea pig if nobody else has yet [8D]
