I'm picking up a TTA and was told the heads use different rockers than that of my GN. My questions are: Who makes aftermarket roller rockers for these heads? What is the stock TTA rocker ratio??
Don't know the answer to your question, BUT, I don't see your GN listed in your sig??? Did you sell it??? All that time spent finally getting it to run a 10...
Talk to ya later...
P.S. I FINALLY got my block back from the machine shop for the 87 T...Hopefully will have it running in the next couple of weeks...
