Re: [FWDLK] Re-Building a 230 Cu. In. Flathead

I agree with Brian. As long as you are not going racing, towing etc. (which
I suspect you will not be with this engine) then they should be fine. They
do have additives to make up for it now a days and it doesn't need to be
added every tank. Just every few. And if you only use the car for pleasure
then it's not that big a hassle to dump in a can of lead substitute every
so often.

I've checked with several petroleum engineers about this question in the
past and
here is what they all told me.  If you have an engine that has been running
for
years and has 40K or more miles, then there is enough lead in there to last
almost
forever and not to worry about the seats.  If however you are planning to
race the
car,  tow a trailer or regularly be driving in mountainous terrain, thus
placing
additional loads on the engine, then they all recommended installing
hardened
valve seats.

As to a newly rebuilt engine, however I would opt for the hardened seats
since
there would be no lead build up available.
