Time-Sert Thread Repair Insert, 8 x 1.25 x 11.7mm Long, 18121
Time-Sert Thread Repair Insert, 8 x 1.25 x 11.7mm Long, 18121
Price: $1.50

Time-Sert Thread Repair Insert, 8 x 1.25 x 11.7mm Long, 18121 is the best thread repair kit available. This size is typically used to repair intake and exhaust studs in cylinder heads, or the medium sized studs in the engine case. Inserts are sold per EACH.

You can also use this to do a slick upgrade to your upright engine; remove the generator stand studs and use these inserts, then use ALLEN BOLTS to hold the stand down! The advantage to this is you will have a stronger than stock repair, AND you won't have to lift the stand up OVER the studs if you ever have to R&R the cooling fan or alternator/generator! Remove the bolts and slide it straight back!

Time-Sert inserts are superior in every way to typical "Heli Coil" thread repair kits (which are usually wrapped wire, very weak and troublesome to install!).

Time-Sert inserts are solid, and also have a flared shoulder that prevents leakage, and locks the insert into place without excessive Loctite needed.

The repair process is to drill out the old threads, then use the shoulder cutting tool (To make room for the insert's shoulder on the top), tap the hole, then install the new insert. Hole will be repaired, and will be stronger and better than it was when it was new, due to the larger diameter holding power!

Los Panchito CNC Ported Dual Port Cylinder Head, 40 X 35mm Valves
Los Panchito CNC Ported Dual Port Cylinder Head, 40 X 35mm Valves
Price: $369.95
DISCONTINUED by Manufacturer, Sorry!

The Los Panchito CNC Ported cylinder head is a fantastic value for medium to larger engines up to around 160hp. Hi velocity ports provide high air speed for an extremely wide powerband. This is a great head for VW bugs, busses and type 3s!

You can't go wrong with these on engines from 1800-2100cc, but they will also work well on medium tuned 1600s! This is a fantastic "ready to run" option for guys building their first "big" engine, being capable of ~150hp with everything else being up to snuff. We do have heads that outperform these, but for the price this is a fantastic choice.

These have 59cc Chambers out of the box, so you can calculate your Compression Ratio. These use the 14mm x 1/2" Reach (long) spark plug.

Price is for ONE cylinder head.

Please understand that these are NOT as nicely finished as the ACN L5-L8 heads. Typically the Los Panchito has some casting flash in the cooling fins that should be "cleaned up" prior to installation, in order to have the best airflow over the cooling fins. When you spend time on this they do run 20-30F cooler than if you neglect this task. However, they do flow similarly to the L5, but flow #s are not the only factor you should consider before spending your money on a set of performance cylinder heads!
Dual Port Cylinder Head, 35 x 32mm Valves, PAIR, 500-400
Dual Port Cylinder Head, 35 x 32mm Valves, PAIR, 500-400
Price: $399.95

Price is for TWO cylinder heads to do one engine.

These are equipped with HD Springs, so they are perfect for cams up to around 290 advertised duration (Engle 110, SCAT C-35, etc). Bigger cams than this will need Dual Springs. These heads are a good choice if you are building a mild engine with a non-stock cam, since you would need to buy new HD Springs and Chromoly Retainers, removing the stock stuff. Why pay for stuff you are going to take off an not use? Use these instead, they have that already! Another beautiful feature of these heads is they do NOT have the #)*($&#)*& step in the combustion chamber, which causes NOTHING BUT PROBLEMS!

These are complete with Valves, Guides, Springs, Keepers, Retainers, bolt them on! Chambers "out of the box" have ~59cc. If you want a different chamber volume, please choose the "CC" option.

Price is for TWO cylinder heads to do one engine. These heads come unported, they can be used as is, or ported for more airflow and power.

Choose from HD Single or Dual Springs, to properly match your cam and rocker arms that you will be using. You only need HD Single springs for cams up to around 290 advertised duration (Engle 110, SCAT C-35, etc). Bigger cams than this will need Dual Springs. If you use an Engle 110 or SCAT C-35 with 1.25 rockers, you will need DUAL SPRINGS!

These heads are a good choice if you are building a mild engine with a non-stock cam, since you would need to buy new HD Springs and Chromoly Retainers, removing the stock stuff. Why pay for stuff you are going to take off an not use? Use these instead, they have that already! Big Valve Heads can only be successfully used with engines that have 1 1/2" or larger exhaust systems, which also means the stock heater boxes can NOT be kept! If you use stock heater boxes or 1 3/8" exhaust your engine will be difficult to tune, and will run much hotter from exhaust back pressure holding heat in the heads!
