lose the 85mm tb just have your stock one ported
40# injectors is overkill 30's should be fine......
stock fuel rails are good to like 700rwhp i think you'll be fine with stock ones
alot of people have LT's in mustangs....
stock lifters will be fine
your stock rockers are 1.7...

leave the stock fuel rails and lifters and use 30# injectors and then ill have it tuned what do you think ill have for rwhp after the head work and ****?
