Can people who take medication for hypothyroid eat high fiber foods?
carburator cleaner should work fine, or brake cleaner
Not at the same timeThose are two different issuesTake them to an atomotive machine shop and have them hot tanked.
Well, hot tanking will loosen up the oil and old paint and if left in over night the scale inside the water jacket areasIF you really want them to shine then you are looking at some major time investmentAssuming you can get all the crud off with some chemical baths or hot tank you will have to buy a polishing kit that fits a moto-tool or a drillIF you can't get the crud off with a hot tank bath then you should ask them to sand blast the headsOnly problem is getting all of the sand out of all of those holes in the headsNot an easy task and I don't think they sell a clear coat paint that is heat resistant and that's what you'd need to preserve the polished look once you spent a week polishing away with your moto-tool and polishing kit.
With hypothyroidism you need to eat more fiber to keep the metabolism goingJust make sure you take the thyroid medcation on an empty stomach with no food for an hour after taking itSome people have found taking the med at night helps.
