Re: Heads

[MO <micher@xxxxxxxxxxxxxxx>]

So what happens with the front and back rail of the intake  where it
mates to the block?  As the heads are shortened in height, the intake
moves closer to the block , and with a stamped valley cover isn't
there interfearance at the rails?  And how much does all this
machineing going to cost? Remember I am on a tight budget with this
engine. ..............................................MO

That way everything is perfect going back on the motor. And if you didnt know they had been cut you would not be able to tell any real differace.
