Default Re: exhaust cross over (heat riser) fill

It's a good idea to pre heat the cylinder head before pouring the aluminum filler.
otherwise the fill chills too quickly and can shrink around the outside. also make sure you melt enough to do it in one pour.
I fill from the intake side,blocking the port side with a little furnace cement and a steel plate securely blocked in place.
You dont want that come out while you're filling! ...unless you like shiney silver shoes!!
