hey there names chico i have a question to ask someone what are the specs on the camshafts i need lobe hieght also how difficult is it to put a new chian and tensioner on this car it already has a double roller on it and is there some thing i need to be carefdull when doing this job txs

Different cams have different lobe heights, Need to have the cam numbers. Your car has been 'fixed' with the double row chain. Not a big deal to roll on a new chain, connecting it to the end of the old, then change the tensioner.
