wanted to find out about procomp and they are using the old
protopline castings which went out of business, the castings are
coming from china like every thing else, even some of the best
tool companies are made in china, dewalt, milwakee, etc. I had
a set of protopline sbc heads and worked great for the price,
went racing and daily driver, the other comany that is putting
out the old protopline is RHS, my canfields were cast in china
as well, and if you check all the cam companies, they get their
castings from china as well, all because the cost of payroll for
it to be made here can't compete with the overseas castings,
Friedrich air condidtioner just closed here in tx and is moving to
mexico to compete with the companies from china. so castings
from china like the procomp heads might be junk, but if you
check your high dollar parts on your car, they more than likly
come from china, deal with it.
