hi guy's

ive done a couple of head off's before (ohc, cvh), be never a twin cam, is the puma 1.7 1999 vintage fairly straight forward to do, like when i take the head bolts out the sump isnt going to fall off, or you have to take half the engine apart before you start taking the head off, i guess it's gonna need valve's, what are the chaces of it fooking the pistons, i dont really want to put another engine in it
