ok i searched and found some stuff but i just wanted to hear people's opinions. im trying to take the rail off and put in 310's, i have the feed line off and now im trying to get the two bolts that hold the rail to the mani off. i saw that alot of people took off the upper mani or they took of the valve cover. which is better to do? and if i take off the upper mani do i need a new gasket, i know it would be better to put one in but do you need to? and did how can you get to the bolts without taking either off, i dont see a good way to get access to the two bolts. thanks for the help.
