However, the second-half introduction of player/manager Gareth Ainsworth breathed new life into the visitors and Wood scrambled home the equaliser after Stuart Lewis had an effort blocked on the line.
Top scorer McClure completed the turnaround 10 minutes from time after collecting Ainsworth’s cross, turning his marker and drilling into the bottom corner.
Ainsworth made two changes to the Wanderers side with the available-again Josh Scowen and Bruno Andrade coming into the team at the expense of Anthony Stewart and Matt Spring.
Scowen had missed the last two matches after picking up his 10th booking of the season. The changes meant that Sam Wood reverted to left-back with Charles Dunne moving across the defence to centre-back. Joel Grant switched from right to left wing.
Wanderers started well with Sam Wood’s left-footed drive being deflected wide by Daniel Leadbitter, before Andrade flicked wide after Scowen’s throw had been flicked on by Dave Winfield and Matt McClure.
Scowen was heavily involved early on and Torquay keeper Michael Poke had to dive full length to his right to parry away the midfielder’s 20-yard shot after Scowen had won the ball in the home side’s half.
Chairboys were inches away from taking the lead in the 11th minute when McClure eluded his marker to meet Scowen’s corner, only for his header to rebound back off the post to safety.
Morgan and McClure combined well down the left in the 18th minute before the former’s low cross was scrambled away close to his own goal by Kevin Nicholson.
Torquay came back into the contest as the half progressed but struggled to create anything against a well-organised Wanderers defence and it was McClure who had the next effort when he headed Scowen’s corner over the bar in the 28th minute.
Andrade tried his luck from the edge of the area after Damon Lathrope gave the ball away in a dangerous area, but the winger’s outside-of-the-boot effort drifted wide.
Wanderers’ hassling and pressurising was a key factor of the first half and again the Blues won the ball near the Torquay goal, but Grant’s low cross just evaded Morgan and McClure.
Despite all of Wycombe’s pressure it was the hosts who took the lead eight minutes before the break. Billy Bodin did well on the Torquay left and cut inside Harriman and Andrade before picking out Jarvis just inside the area and he fired past Archer via the aid of a deflection.
Ainsworth’s men responded well and Poke kept out Morgan’s low strike with his feet a minute later.
Bodin was the home side’s biggest threat in the first half and he had a 20-yard free-kick tipped over by Archer before clearing the bar from a similar distance.
Blues’ second-half plans were disrupted after only four minutes when Grant limped off and was replaced by Ainsworth.
The home side were much improved after the break and Rene Howe headed over before former Wanderer Elliot Benyon saw a shot superbly blocked by Winfield.
McClure escaped his marker to get to Morgan’s dangerous cross first, but he couldn’t get enough on the ball to turn it goalwards. The striker then saw a shot blocked by Brian Saah. Scowen’s resulting corner found its way to the far post where it hit Stewart and went wide.
Ainsworth made a big impression after coming on, firing in a number of dangerous crosses, but it was the hosts who looked more threatening and Winfield threw himself at Bodin’s shot when Howe found the winger eight yards out.
Wanderers got the goal their overall display deserved 14 minutes from time. Morgan did superbly to reach the byline and his cut-back reached Lewis whose shot was blocked on the line, but Wood was on hand to smash home from close range.
It was 2-1 to the Blues four minutes later when Morgan found Ainsworth who crossed for McClure. Wycombe’s top scorer took a touch, turned his man and drilled low past Poke from six yards. It was a fine finish from McClure who showed great composure for his 10th of the season.
Torquay pushed forward late on, but Wanderers lead magnificently by skipper Winfield repelled the threat and saw time out to secure all three points.
