I finally got my RHS aluminum heads that were ported and milled on my 355. I'm not sure how much was taken off. They went from 64cc chambers to 61. I also had a weiland stealth(their version of performer RPM) non-vortecintake port matched. I ordered from negs w/ install kit (bolts and gaskets). The gaskets are cheap paper jegs brand. The right side lined up perfect. The left is 1/16 or 1/8 of an in off letting the bolts line up. Should willow the holes out? Could it be the gaskets? Do should they have trimmed the intake to fit the milled heads?

Usually depending on how much was milled when it gets so far it knocks the alignment off so the intake has to be cut to the same angle as the heads are.

I wouldn't thing that 3 cc's off the chambers would be very much. I may call Speier Racing up and see what they thinks. I would think that since they did both of them at the same time that if they thought it would be an issue they would address it.

Normally .006" cut per cc. so .018" cut = 3cc. Flat Milling.
.0075" per cc. when Angle Milling.
I would think they would've machined both for proper alignment.
