I am am building a new motor, I am going with EJ257, P&P WRX heads along with cams. Looking @ the price of Helix they cannot be passed over,I did a search but all I got is bitching about the packing.
I would like to get feedback from people who run them. Are they true 264 or just labeled 264. Are they ok to use or should I just save up and go with DPR or cosworth?
