With the recent death of an innocent/not abused F20C engine from normal driving (check here) I am really thinking twice about this mod. I really don't want the collision between the valve and the piston. I hope the strengthened springs and extra cam lift may avoid this. Has anyone use toda gears with their vortech? Is there any dyno gain as well?

 

found a couple of interesting threads from the search...some how it did not work last night

so a little bit too much overlapping...may not benefit a FI application. IS this true?
