Experts please help... (quick HP questions)

shorty headers come in equal and un equal. i don't think theres a big enough diff in the two power wise to matter much. i've heard the un equals take up a little less space and are easier to install......but can't comment personally as i have equal lenths.

intake manifold will help some........between 10 and 20 hp depending......and the type of manifold you get depends on what your going to do with the car down the road as which is the better to get

to get 260 rear whell horsepower you'll need to do something with the heads.....after market or have the stock ones worked over.

if you already have a manifold a bigger maf meter and tb may give you some, but there comes a point where to get much more you have to do something with the heads.

what gears are you running?? most will tell you to start there after doing some exaust stuff.

usually it goes gears/exaust first then the other stuff...
