360 LA installing Promaxx Aluminum heads

It depends on what the specs are and if his numbers are correct and accurate. The hole in the rocker comes in at .874. I would have expected that the target dimension would be .875", who would pick .874? That would be the first question I would ask HS, what should the hole in the rocker be and if it isn't where it should be, they should fix or replace for free. If the hole is anodized, they may have gotten it too thick or it may not have been big enough to begin with. A couple tenth's per side add up to too tight.



Harland Sharp has a vendor that does their anodizing work. And although I use rockers with bearing I don’t thing they anodize the inside.
