![]() Place a new intake manifold gasket (the same you will be using for assembly) in position.Ĥ. This will make it very easy to see the scribe lines you will make later.ģ. Coat the manifold gasket area with Blue Layout fluid or a light coating of dark colored spray paint and allow to dry. Thoroughly clean the cylinder head gasket-mating surface and intake manifold gasket-mating surface using PRE (#10041Z), acetone or lacquer thinner.Ģ. Use a spring compressor to avoid damaging the valves during removal.ġ. Following your vehicle shop manuals, remove the intake and exhaust valves. ![]() This method assures that the cylinder head intake ports match perfectly to the intake manifold port openings. GASKET MATCH THE CYLINDER HEAD INTAKE PORTS TO THE INTAKE MANIFOLD Pay particular attention to the exhaust cross-over, which is usually clogged with carbon and will affect engine performance if not cleaned out. Also, the life of abrasive materials will be greatly reduced. Otherwise, you will not be able to tell if the parts are suitable for porting. “Hot Tanking” is recommended for thorough cleaning. Remove all carbon from combustion chamber and exhaust ports. Warped cylinder heads and manifolds should never be re-installed. Do not attempt to grind-out cracks in the castings. If you have any doubts about their condition, have them checked at a reputable machine shop in your area. Cracks can be located with the MagnaFlux Crack Detector. This is done by 1) “smoothing” (or, grinding) the passages in the intake manifold so that they are the same size as the gasket and cylinder head, and 2) removing “rough cast” or “flash” imperfections in the cylinder heads and exhaust manifolds.īe certain that they are not cracked or warped. When you “port” an engine, you remove imperfections and restrictions between the combustion chamber and intake manifold and, therefore, increase air flow. More air means greater engine efficiency – both more power and better fuel economy. More valves means more air moving through the engine. This is one reason why we’ve seen a turn to multi-valve engines in recent years. The better an engine pumps air, the more efficiently it will operate. Internal combustion engines are sophisticated air pumps that pull in an air/fuel mixture, compress it, ignite it, react to the ignition and expel the exhaust fumes. Buy a top-end gasket kit and you should have all of them. You will also need the cylinder head, intake/exhaust manifold, and carburetor base plate gaskets. Your kit should contain the following items: We also recommend wearing a long-sleeved shirt to protect your forearms from any flying particles. Rings, bracelets, watches, etc., should be removed to avoid the possibility of their getting caught on the cylinder head or wrapping around the mandrel on the grinder.Īvoid loose-fitting clothing. It is essential that you, and anyone else helping or watching, wear proper safety equipment to avoid injury from any metal particles. The porting process involves removing metal with a high-speed diegrinder. Safety Goggles and Dust Mask must be worn by anyone in the area where you are working. NOTE: For reshaping ports and valve guide bosses use the carbide burrs listed below. It is designed to help get the most out of an existing configuration, not for heavy modification or reshaping of combustion chambers and ports. The Eastwood Cylinder Head Porting Kit is designed to allow the home mechanic, using little more than a high-speed grinder, to clean, polish, and lightly modify the ports on cylinder heads.

I am trying to get my side business going and cutting everything out by hand now and hand finishing with die and angle grinders and it is really slowing me down. So what should I do? Just use the Hobart? Get the Razorwled? Wait for the Cut 60 issue to be resolved? Or the Everlast 52i? I was going to pull the trigger on the Cut60, until I learned about the potential interference issues. I was looking at the Razorweld, but it is more than the Titanium 45 with a lower duty cycle and 8 week wait. Now the hard decision…I have a Hobart AirForce 40i that I could use, but I did not want to tap into the wiring for the torch control in case of warranty issues down the road (maybe I am worrying too much about that). ![]() Thank you everyone for your help and input.
