I’m looking at my options here. I thought I would have purchased the valves already. Instead I’m still researching. A single MB intake valve (1800530401) in Canada cost as much as the complete intake set from Intervalves. From what I read, top shops are using the brand with great success.
MB valve in the pic below was previously installed. Could this just be the luck of the draw? Due to the pours surface it’s very hard to lap. My other concern is structural integrity.
