H&L Performance is famous for their head porting, all done by hand,conventional tool room service, milling and turning
IT’S A DYING ART FORM - HAND-PORTED CYLINDER HEADS… The process of modifying the intake and exhaust ports of an internal combustion engine to improve the quality and quantity of the air flow, is a task that today’s generation of techs would rather leave to machines… but there are a handful of rebel-minded innovators left in the United States that continue the art of head porting by hand.
Is faster always better? Today, in the rush of instant gratification, most people C&C-port their heads, meaning they take a cast head, which is of course subject to casting imperfections, and then they have a C&C machine port it, running off of a computer program that ports the heads, one after another, exactly the same.
Anyone who knows anything about high performance engines, knows this… no matter how well-built the engine and no matter how well-planned the part configuration, without proper head flow, every effort towards performance will be futile.
MACHINE vs. MAN… Customized parts, like heads for instance, takes time! So, where’s the middle ground in all of this? Well, H&L believes excellence can be achieved through that perfect combination of old-school precision and state-of-the-art knowledge, machinery and tooling.
Head porting by hand is a unique shop experience for every project. It allows for correction of any imperfections created during the casting process. Best of all, hand porting includes the experienced touch and feel of a machine shop artist, like H&L Performance’s highly elusive (and widely respected) Tom Haner, who has been head porting by hand for thirty-five years.
Customizing your bike is an investment in a piece of art; a show of excellence when ridden and it’s worn like badge of honor to represent the long history of the motorcycle engine evolution. Hence the saying, “Don’t rush the beauty if you want to feel the beast”.
H&L Performance’s heads are each flow-tested on a top-of-the-line Superflow Computerized SF-600 Flow Bench, with velocity probes that ensure maximum flow with optimal velocity. With well over 50 years of combined experience, and a machine shop that offers the best equipment money can buy, H&L Performance has perfected the art of engine rebuilds, from stock configurations to boring and stroking to reach absolute maximum potentialJESSE JAMES’ BIKE “Mighty Whitey’s Wheelie Machine”
We wanted to get our motors to the West Coast, and a friend of mine from a predominate motorcycle club said he had a friend who was close to Jessie and could hook us up, but we’d have to send a motor out for them to try. When I got in touch with Chopper Dave and Bill Dodge they said not to bother sending a motor because ever motor sent tot hem they end up sending back blown up. I said that obviously the motors sent to you don’t know what the fuck they are doing.. you will not blow our motor up. Period. I sent the motor and told them to call once it was running. They called us back and said it sounded great, and that they took it around the block- I asked what they thought, they said they didn’t know because it wasn’t broken in yet. I said go out and beat he living fuck out of it and if it blows up I'll know I didn’t build it right- so they did-
ROBBIE KNEIVEL’S WILD RIDE
I showed up to film delivery of the motor, but Robbie wasn’t there, his people said he was always late. I figured I already wasted a day of work being out of the shop, so I asked them where is the closest place to have a beer. ½ way thru my 2nd beer I get a phone call that Robbie had arrived. Figures. On our way back we stopped at McDonalds because no one had eaten, and we got back, everybody was kissing his ass because of his stardom, except me ‘cause I really couldn’t give a fuck. I was then told I was up 1st for interviews, Robbie came over to brush french fry matter out of my beard, I swatted his hand away and said don’t fucking touch me… He smiled and said, “you don’t want your mother to see you on tv like that do you?” I said, “good point!” I did my interview, then stepped outside for a cigarette, shortly thereafter Robbie came out for a smoke, he rolled his eyes, tipped his head the way Robbie does, and said, “what the fuck is up with those people?” I said, “what do you want me to tell you, they are kissing your ass”.
Robbie invited into his motor home for a drink, to which I said, " hell yeah", and asked, “you got Jim Beam”, and he said, “I have Jack Daniels, Jack Daniels and mustard”. So I said “I’ll have a JD”. ½ through the bottle of JD his people came to find him, and I can tell you this- no other interviews were completed. Then, just like that- he left. But not before we exchanged numbers…
I warned him that if we hung out we’d end up in jail together, to which he responded, “I’ve been arrested in 16 different cities, why would one more make a difference”.. That is Robbie, he is just a cool guy…
