I have a cally 16v. Just put a new head on it as the old one was porous. When tightnening the bolts one of the bolts pulled the thread and another was about to go.

My dilema is its an H reg Virtually mint. Now do i waste my time repairing it or do i break it and sell the bits??

Also i cant get the crank pulley off as the bolts are F***ed and will probably have to drill em off.

Worth the work or not??
