i have had a set of heads on order at speedway since 9/24/2016 and now am told that not only has the price gone up , now “possible ETA is 8/1/2017. Really???

I would love to run these on my 53 Customline but I am getting impatient with the wait.

What is going on ? If you are going to no longer supply these please say so and I will buy a set of Edelbrock heads (my second choice).
