The 20-year-old hit-man joined the Ewood Park club last week in a £1.25 million move from Third Division outfit Huddersfield Town.
He made a sensational start to his Rovers career by scoring the winner in their 1-0 away victory at The Riverside.
The former Terriers trainee revealed he was nervous before Saturday's match but felt he needed to remain cool under the pressure of the expectation on his shoulders.
"I was very pleased with the finish and I was surprised by how cool I kept," said Stead.
"You think, if you get a chance, just don't snatch at it.
"I was very nervous when the manager told me I was starting on Friday, but I told myself to deal with it and just make the most of it."
Stead started up front with fellow hit-man Paul Gallagher at Boro, as Rovers boss Graeme Souness decided to leave the more-experienced duo of Dwight Yorke and Andy Cole on the bench.
The fiery Scot admitted he is prepared at all times to change his line-up, if he feels it is necessary.
"I don't think anybody can expect to be in the team," said Souness.
"I have shown in the past that I am not reluctant to go with youngsters and I felt Paul and Jon were the right pairing for the game.
"On Wednesday, when we play Newcastle, I might go back to Yorke and Cole."
