Very funny with the last name bit. I already have an aeromotive FPR. But as far as line size which is better 6an or 8an. And don't worry bout the money. I didn't really cut corners on this build. And the guy I am goin to builds outlaw quarter mile cars. He is getting the clearences down pat. He has been doing this 20 plus years. He is a well known LI builder that was recommended by a friend. He is getting the clearences super close due to the fact I am going to DD the car. Yes deburring the water passages and coolant galleys will be done. Anything else out of the ordinary especially heads wise. And the vacuum hose? Still need to know which diameter and how many feet. Also I have formed silicone return hoses for the turbos. Should I not use those and go oem rubber. I have the ss lines with the restrictors on the feed side
