it has DE wesico's right now .....some day I want to pull it again , and throw in some VE ( JE's or CP's ) in 90mm in the motor, then I can run these darn 20V cams I have sitting here , but then I should also put in some larger stainless valves since the stock VE exhaust valves are smaller then a DETs and CNC the combustion chamber and machine it to the 90mm bore ........just to aid in power production , this is similar to what mike had done to his head , he made the 664.9whp on like 20lbs on race gas in his 90mm super worked Mazworks head white SE-R , my only problem with tearing the motor down is I am pretty happy with the power it has and with this setup there is still alot left in it , not a lot of reason to change it right now , other then I can and it will build more power easily ....
