Great running from Canaan Smithies, Cameron Wroot and Josh Mills made space for Kruise Leeming to storm over the line for his first try in the corner.
Bowling's defence was again put under pressure as Corey Smith, Zack McMomb and Gareth Nicholson made yards for Leeming to score a further two tries and conversions.
Siddal conceded two tries before half time and West Bowling had more chances after the break.
But the Siddal defence stayed firm and Connor Greenwood intercepted a pass on the try line leading to Siddal going back on the attack again with man of the match Luke Saltonstall making a break to set Leeming up for his fourth try.
Great running from Max Dow, Daniel Parry and Nathan Redmond then led to Leeming powering over the line for his fifth and final try which he converted.
Leeming's quick hands then helped Rob Holroyd to burst over the line to complete the scoring.
King Cross built on a dramatic start as they won 13-4 at Keighley.
The home side kicked off deep into Cross territory and the ball was moved quickly with Shohaib Mahmood striding over under the posts, Ryan Sweeney converting.
Some speedy passing opened up another gap for Mahmood to race in, Sweeney again converting.
The second half was an exciting battle, Keighley finally finding a way through out wide for their first and only try of the game.
But Cross intensified the pressure and in the final minutes Sweeney surprised Keighley with a fine drop goal to seal a superb effort.
