Need some help !!!!!!!!!!!!!!!!!!!!!!!!!

While I would not list rings as the #1 likely cause, I'd not depend on any compression or leakdown tests to be totally accurate with any significant amount of oil in the cylinders.

BTW, what guide seals were used? The ones that came on the Edelbrocks? They are pretty snug. Are these parts (heads, seals, intake) all new? (Pix all look new..)

If you had another set of gaskets, I'd put them in place with the intake and use feeler gauges at all 4 corners, top and bottom, to check that the gaps are all even, plus do a close visual inspection at all 4 corners. I would not expect to reliably close up more than a few thousandths gap difference top to bottom.
