FOR MILWAUKEE M8 MOTORSAV&V™ Extreme Duty Manganese Bronze Exhaust Valve Guides (6MM) AV&V’s Manganese bronze valve guides are CNC machined. Our alloy allows you to fit both intake and exhaust valves at tighter clearances for better heat dissipation, longer engine life.
Tapered & radiuses nose for easier installation and better air flow.
Unfinished I.D. ready to be easily finished with AV&V’s Carbine reamers.
Replace your factory powdered-metal retainers and stamped keys with these highly durable, high quality chrome moly forged spring retainers and steel keys. Don’t risk a catastrophic failure with substandard stock parts in your performance application!
These superb valves are one-piece forged from a racing grade stainless steel alloy with a hard black finish and a bearing quality hardened tip at the end of the stem to prevent premature wear with high-lift applications.

AV&V’s CNC-machined valve guides are made from Manganese bronze alloy which allows tighter clearances for improved heat dissipation, quiet operation and long life.
AV&V’s valve seals are made from a special Viton compound that can resist higher temperatures than standard Viton seals. Manufactured to fit tighter on the guide – stays put! For this reason we recommend AV&V’s Valve Seal Driver tools for installation.
When it comes to high performance valves, Pro-Street out shines the competition. One-piece stainless impregnated by a special German process (.002 deep and .0002 surface build-up) to improve wear performance in cast iron or nickel-bronze guides.

Matching the correct valve spring kit to your cam is very important to maintain proper valve train control. Crane’s valve spring kits are an excellent choice for many performance applications.

To make big power, you run an aggressive cam profile with high lift.To maintain control of the valve train, the valve spring needs to provide adequate seat and nose pressure, and be able to last a reasonable life cycle in a sometimes brutal environment. In today’s performance engines, this is one of the most highly stressed components; for this reason, you should only consider the highest quality spring you can buy.
We’ve never been big fans of the shoulderless valve guides used by the factory in EV & TC heads, so we designed our own. Our ductile cast iron Step-Lock guides have a shoulder that helps set the guide to the correct depth, and, in the event that the engine is severely overheated causing the guide to come loose in the head, allows the lower valve spring collar to capture it, keeping it in place. The top side of the guide is machined to accept larger .531" ID seals while the port side is tapered to enhance flow around the guide. Requires use of stepped lower valve spring collars (our Crane spring kit collars work fine without modification). We offer lower collars to fit the spring kits we sell for use with these guides. Sold each.
