Hola, estoy buscando algunos sellos de válvula buenos para mi cabeza sin tener que modificar las guías originales, he visto algunos en venta "M-6571-A50" que dicen que se adapta a guías de 0.550 "hasta 0.570", pero no estoy seguro de que sea así, un poco de ayuda y si conoce algún otro sello, se agradece la ayuda.
Gracias

If doing a positive type of seal, the guides will need to be machined accordingly. Those positive type seals are made to accommodate guides that are machined to 0.500”, 0.530”, or 0.562” at their tops. If using stock diameter valves springs, then the umbrella seals that come in the gasket set will work without guide modifications assuming the retainers have enough clearance to the tops of the seals at full valve lift. Increased valve lifts must be compensated for. If going with a smaller diameter valve spring, then some upper guide modifications may be required if still wanting to use the umbrella seals.

Si se realiza un tipo de sello positivo, las guías deberán mecanizarse en consecuencia. Esos sellos de tipo positivo están hechos para acomodar guías que están mecanizadas a 0.500 ", 0.530" o 0.562 "en su parte superior. Si usa resortes de válvulas de diámetro estándar, los sellos de paraguas que vienen en el juego de juntas funcionarán sin modificaciones de la guía, suponiendo que los retenedores tengan suficiente espacio libre para la parte superior de los sellos en la elevación completa de la válvula. El aumento de la elevación de la válvula debe compensarse. Si va con un resorte de válvula de diámetro más pequeño, entonces se pueden requerir algunas modificaciones de la guía superior si aún desea usar los sellos del paraguas. [citar]
Gracias Ted, ¿son los sellos estándar que vienen en la calidad del juego o dan problemas?
