The Winged Lions did just that.
Pius X raced to a 26-7 lead after the first quarter en route to smoking the Pioneers, 78-47, at Strom Gymnasium.
King, a sophomore, scored 11 of his points in the first period, including a 3-point basket at 4:45 that triggered a 30-0 run between the middle of the first quarter and start of the second stanza which enabled the top-seeded Lions (18-7) to pull away comfortably.
They compounded the effort in the first eight minutes with a 22-5 rampage in the second quarter for a lopsided 48-12 advantage by halftime against the Pioneers (5-19).
Pius X will face Devon Prep, a 39-38 winner over Lower Moreland in the first game of the doubleheader, in Saturday's district title game at a site and time to be determined.
"We tried to come out and set the tone," King said. "We wanted to let Devon Prep know we were coming."
King was one of four Pius X players to reach double figures. Joe Pritiskutch came off the bench to swish 17 counters with three treys while Chad DiFebbo (11) and Mike Urie (10) on a night when coach Randy Reber was able to give 13 players court duty.
The Lions also held a distinct 44-25 advantage in rebounding. Chris Flick grabbed nine boards while Mike Curry and Urie had eight each and King seven.
"We knew we had the height on them," King said. "It is always good to get out early."
Reber was glad the Lions answered the bell.
"I wanted us to come out and perform well early," he said. "But I had no idea what would happen after 14 days. It happens every year, but each team is different.
"We were sluggish to come out. Then we went up tempo to create some things and force it. We had some players who did not get a lot of minutes. We tried to do what was right. We had to get back and get ready for Devon Prep."
Christopher Dock held a 7-4 lead at the 5:01 mark, but that lead was short-lived.
After his triple, King converted a fast-break layup to help get the Lions roaring and leading the rest of the way. DiFebbo made two foul shots and then a trey from the top of the key. King hit another layup and Dave Bilinski a baseline jump shot to give Pius X an 18-7 lead at the 2:53 juncture.
Dock, which shot 10-for-23 at the free throw line, had two missed attempts at the stripe by Dean Haller at the 2:40 mark of the first period. Then Pius X reeled off eight straight points to end the quarter up by 19 points.
Flick canned a shot with a feed by DiFebbo and Pritiskutch drilled a shot from the left baseline. DiFebbo made two shots at the foul line and Pritiskutch's jumper made it 26-7.
"Joe comes off the bench and gives us a big boost," Reber said. "Matt King was aggressive early. He didn't score in the Final Four, but he guarded (Owen J. Roberts' Chad) Piersol and (Spring-Ford's Ryan) Kraft for the betterment of the team. He was looking for offense tonight.
"We had unselfishness and good bounce. Mike Urie played with a lot of confidence. He is our first big man in. Joe and Mike we rely on them. Brett Ames had a pretty good little stretch and Brian Hartsell handled the ball."
Ames ahd two fourth-quarter baskets, one a 3-pointer. The Lions buried seven shots from long range on a night when they shot 33-for-62 (53 percent) from the field and 5-for-6 at the foul line.
Dave Volpe paced Dock with 22 points, including three triples. John Tyson made one trey in each period to finish with 12 counters.
The Pioneers shot 15-for-49 (31 percent) from the floor.
