Sevenoaks Town chalked up their seventh away Bostik South East win of the season at Hanbury Stadium on Saturday.
Jack Miles headed home his second goal of the season after only nine minutes to claim the points.
And he might have been celebrating again a second 60 seconds later as Oaks made it a frustrating day for the West Sussex play-off contenders.
Former striker Kenny Pogue faced his former club, just weeks after moving, but had a quiet game, eventually substituted with 16 minutes left, as Oaks held onto their early lead and almost added a second late on.
They went in front when Miles unmarked at the far post, heading in Dan Parkinson’s well flighted corner, an assistant flagging to confirm the ball had gone over the line.
A minute later the ball fell to him again, left free at the other post following a free kick but fired over the bar from around eight yards.
Callum Saunders was Heath’s most dangerous player - first shooting just wide of the far post, before being denied five minutes by Ben Bridle-Card’s fine save, on his way to a second successive clean-sheet, in the week he committed to the club for next season.
It proved Heath’s best chance of the game as Oaks frustrated them with a solid display, passing the 40 point mark, a notable achievement in their maiden season in Step 4 football.
Lauris Chin looked lively in the first half while fellow new-boy Kyle De Silva went close to just after the half hour, seeing his free-kick fall just wide.
Clear-cut chances were few and far between In the second half, - before Frankie Sawyer went close twice in stoppage-time.
