Im posting in the all-motor section with hopes that I get a technically knowledgeable response. My apologies in case this inquiry is not technical enough to warrant posting in this thread:

Since there is a more aggeressive valvebody available for the 4-speed unit I was wondering if anyone knows of a similar upgrade for the 5A. I think a performance valvebody would be sweet with the manumatic, no?

 

I dont know, but you could contact Transgo (www.transgo.com).
