question about vk45 valves. ive read the fsm and have compared the 2 dimensions. only real difference is the 1mm smaller vk45 valve. i have also read forums that speak on them but they all seem to be speculation. like if or maybe. i want to know if the valve keeper position would be a problem ( highly doubt) but mainly if there would be any clearance issue with the tappets in accordance to the revup cams because of the slightly shorter valve. will i need a shim there or will it fit just enough. i also plan to double shim hr springs.
Ps. this is for a vq30 HEAD....
