I am installing new heads and the roller rockers dont line up with the tip of the valve. Do I need the isky adjustable guide plates or is the head machined wrong. see picture
i have the same problem on my motor ajustable guide plates will fix the problem if the rocker is on an angle like mine but if your rocker is on straight and you have that problem than the guide plated wont fix it i would need to see a picture of the top of your rocker to be able to tell you can see how my guide plates are holding my rocker crooked

If the op has the same prob as you I do recommend the adjustable guideplates.
And I would like to see a top shot of his also, I can see why you needed them but can't really see in his case due to his pic angle. Nice pic by the way.
