Premier Power F155 Upgrade

Depending upon how the cylinder head has been machined by Ford it may be necessary to remove the cylinder and modify it to suit the new camshafts. Should this be required a head gasket and head bolts will be required along with additional labour to carry out this work. This is not the case on all engines but we have to make you aware before we start the job.
