But the water outlet relocation mod is another good one Where the head is drilled and tapped for multiple exit points If some has a pic that can post I can't seem to find any on net Title: Re: old school engine Mods Post by: colt on February 08, 2014, 12:05:53 PM Just thinking out loud; if you get a late head, the one with two tapped holes where the temp sender and heater fitting go, it would be easy to convert to two extra water outlets, two fittings and some plumbing.
I'm sure the racers use these heads to get better water flow back from the back of the head. People still have the Vauxhall cranks done, pretty expensive though I would imagine. Colin.

As described so accurately by "Keith EFFCEE" "This mod was common in Grey motors that engaged in combat on the race track. Due to the poor design of the water circulation throughout the engine, the Grey Motor developed steam pockets in the head when in full war cry, as a result, heads developed cracks and headgaskets felt the need to be elsewhere with great regularity. To solve this problem the thermostat was blocked off and holes were drilled at even points along the head. A coolant "manifold" was then made up to allow steam pockets to escape and return the water to the radiator."
