well here's my question my current setup is toda A's wih H/I/E and a hondata S200 and I just got it tuned I made 180/125 to the wheels I have a stock bottom end with just a 2 layer head gasket. I am currently getting a head done port polish and new springs retainers valve springs. I am curious if just getting the head done and a single layer head gasket with another good tune if it was possible to hit 200 wheel horse on a mustang dyno.

 

anyone

 

With "A"s and good tuning-maybe...
Upgrade to Toda"B"s, you should hit 200 without too much difficulty, it's been done before.
