These Heads any good?
14096217...55-86...350..........Crate motor, 285hp/300hp, 64cc chambers,
72' or 90' center intake manifold bolt angles
with these upgrades. Looking to put them on the 327.
these are the 21 degree heads and have the 4 center bolt pattern for the valve covers.
the heads were rebuilt by a professional shop, and have:
5 angle valve grind
Crane valve springs with 110 pound seat pressure
Teflon valve seals
machined keepers
Tell me what ya think please!

Yes they're good heads. Even better when ported.
Professional Products makes intake manifolds
that have a special center bolt adapter arrangement
that symplifies the center bolt angle issue.
If you'll be getting a new intake manifold, check these out.
They also cost less than the others.

If you have the mechanical know-how to remove the top end, putting it back together with the new heads and intake will be self explanatory.
'Cept for the distributor alignment, but if you do a search, you will find in upwards of a hundred million threads on putting distributors in the right way.
