Valve seats

[Rich M]

Mike,
I've recently been investigating the options also (1980 RS2000 - 2L pinto);
There will be a 'real' additive available in the next few weeks in the UK
called Tetraboost. It is being manufactured specifically, contains
tetraethyl lead in a Toluene base! If you are interested contact Nik Cookson
at Tetraboost, London - 0181 870 9933.
I've enquired about hard seat inserts and been quoted £100 to supply and
freeze fit 4 hard seats in the Pinto head. - seems the best option really,
ends all the messing. That was Paul Inch Engine Services, Plymouth 01752
255563. He considered it unneccesary to renew valves or guides purely on the
grounds of the issues of unleaded fuel.
