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

Thanks for the help, I forgot to put it in English

i use 289/early 302 valve seals, i trim 1/16th from the skirt. have used them on 3 ys so far,and they all have the drain tubes removed,deeper groves in cam so there is lots of oil to rockers and pushrods etc. no oil consumption or smoke

Thanks for the reply, but I would like to know of any valve seal that fits without modifications

rock auto sells the proper ones.

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.

Gracias Ted, ¿son los sellos estándar que vienen en la calidad del juego o dan problemas?
