That was stupid. Lucky to be alive with that small of a brain. I used a set of Chinese castings for heads, and a matching intake. The match at the intake ports was literally perfect. I tried three different intake manifold gaskets before I realized that unless I ordered them from the same company the heads and intake came from there was never gonna be a match. When I got those, they were perfect. The intake ports in these heads were moved up, and over a little. The pushrod holes in the heads were moved too. All that because the intake valves are 2.060" in diameter and the pushrod needed moved over to better center the rocker arm to the valve stem. Sadly, there was no literature about any of this offered by the Chinese company. To use these heads, I needed to get everything from Speedmaster. Someone trying to run them with an Edelbrock intake would be chit outta luck. The product is great with a little attention to detail. The valve job wasn't stellar, so it was redone. The springs needed better locating seats...so they were added. But as far as fit and finish, these parts are excellent for the money. Oh....on port matching, what you posted is dead on. I usually do.
