Hey guys, you're site poped up in my referal list for Mazdatruckin so I figured I check it out.

Anyways several of us truck owners have had severe problems with valve float, or the cam followers ramping of the peak of the cam lobes and smashing the crap out of the flanking side of the cam lobes. Rumor has it that some Miata valve springs fit. I doubt miata valve springs will be enough, especially with a regrind cam because of the heavier valve train and higher lifts used in the trucks because they are 2 valve per cylinder.

What other valve springs do you guys use to beef up you're performance engines? Please list known specs and if machine work or special retainers were required.

Thanks,
K6
