Missed on this combo?

I wasn't impressed with the bloomer heads from the go, post 411.

There are issues with that combo, twice now...****, what is this.. heads you lose?? you could say that.
I don't like the heads, both pairs. This is an example of numbers and their importance to where they are in the cam range...and what they mean by how soon they come in. Dyno sheet would answer much of this better.. but mike said they were LOW...so anyone can speculate.
Really needed to be getting those cranking numbers, I don't like that manifold either for this combo.
Rod's nuts are on the line, so I really have no doubt he will cover your, by now, very sore arse and get you a better set of something.
