The cams are going back as they are not 9.15mm lift they are like 11.25 lift gutted.
Cheers for the help guys. It all a learning curve and i dont really mind if it does go bang and take the block with it

The block is porous so will be building a new engine soon.
The ignition mapping is the bit that worries me. Can i map the igntion with det cans and without egt's? Do i advance it until i get det and then pull it back to get it in a safe zone but with better response? I know my ignition map at the moment is really safe so i know i can get more out of it.
Here is my ignition map.
Would in the best world if det wasn't an issue advancing it through the whole rev range or just as the car starts to spool ?
