Hello, I have a set of '906 heads that were cut for double springs and p/c seals. Was thinking of using single springs w/dampners, '933. This would be for a high perf. street car.
My question is, it seems the spring would not be supported/located at the base, as the step has been removed. Is this OK or should I use another set of heads?
Here's a pic of the head I wanted to use.

Here is a pic of a head as stock, without being cut showing the boss at the base of the spring

Any comments and suggestions would be appreciated.
Thanks, Jeff
