Cylinder Head Engineering

OH... no ..... outa room on the valve table... just finished valves for a Perkins 6 cylinder , And a Case 3 cylinder , add that to the others, Now it looks like an army of soldiers... lol .

Grinding valves ....

K.... so we are going to rough in the hard seats we just installed .

Working on the little ..Triumph Spitfire Installing hard seats so the unleaded fuel Doesn’t eat away at the exhaust seats

Can’t use the golden nugget

A BAD RAP ? ...... Sometimes that’s what happens when things don’t go right with an engine , this olds I tore down appeared to have good machine work done but is no good now , who’s at fault ?

Calculating deck height on a big block Chevy stroker build

Finish honing. The Kawi !

Ok... finally finished the Kawi. GPZ1100. Big bore multiple cuts to keep cylinder round as the bit comes out of the case. , Used the bigger Kwik Way bar , not much room left . Finished with two thou one and a half Ten thousands of an inch clearance.

Final assembly, These babies are ready. !!

Here is a vid on setting up spring heights on a performance engine . Makin it right !

K... so here we go. Got the heads set up and doing a deshroud cut on intakes and exhaust , this opens up the window and let’s the engine breathe. It’s like having a slightly bigger port but still having velocity of a smaller one . Higher velocity makes and engine more responsive in the lower to mid RPM. A cut on the deck surface with a diamond bit makes a good straight and smooth surface for a Cometic MLS gasket . A slight buff of this surface takes away that nice shiny look but it is easier for head gasket to seal under boost. My elliptical grinder is used to grind the valve seats on all high performance and racing engines . It takes twice as long but makes for perfect seats These babies are ready to go !!

K...so got in a pair of SVO Y303 heads , off a 5-o Mustang , ran a few years with nitrous, and a few years with a supercharger, was on the duno getting a tune and .. WOOFF.. blew a head gasket. So... a set of stainless Manley valves,. Comp Beehive Springs , comp retainers and locks .

And now for something completely different !!
