Hello and welcome to just answer. Let me see if I can help you with this. Do you need to replace all 16 lifters?
Ok, figure on about 4 hours labor (so at $100.00 an hour that would be $400.00 labor), the lifter's are about $30.00 each, gaskets will run about $60.00. figure in about $30.00 miscellaneous, add it all up and your estimate will be about $520.00 plus tax.
