well after 2 sets of head gaskets in 700 km i decided after alot of thought that i has to be my efi f'ing up, so u pulled the efi and changed the: intake and cam and am currently installing a carb, i am nearly finished the project and hope to have it running for the weekend. my pride is hurt, but i have run out of $$$ and patience to solve the efi problem, hopefully i have this solved, on a side note it sould be arround the 350+hp mark. the comp cams cam box had the wording "extreme" on it
