Thanks - I will be ordering it today...

If your block has been decked, that means now the heads are sitting a little lower and farther out than stock on the block. By machining the intake you will undoubtedly almost double the offset of everything ie: bolt holes, port alignments and so on. Do like Bill suggests and use the afore mentioned gaskets.

I'm a retired toolmaker and I know what I'm talking about as far as machining metal to try and make fit.

Bill, Mestorod and Ken;
Thanks for the advice...
I will be installing the gaskets Bill recommend and the permatext sealant mestorod recommended.

Ditto...36 years before retiring two years ago.

You can also go to the Edlebrock site and get the torque and sequence for that manifold if you don't already have them.
