Hi Raj that compressin ratio sounds ok but you will be safer getting a dummy build done the reason being with the xe conversions the piston is sat down the cylinder so there is no chance of clipping the valves where as the forged piston needs to be measured acurate because the piston will sit flush with the block and the compression will be lowered in the bowl depending on the piston. I have had the cambelt slip on a full zetec due to silly powder coated verniers and it never touched a valve because of how the piston sits in the cylinder .
