Holley carburetor Viton seats

[Gene M.]

Any of you guys have a Holley part number for 67 3810 Holley 300/350 hp carburetor Viton needle & seats?

Are Viton a different color? My Holley HP book says they can be any color. The book makes it sound like all the tipped needles are Viton. Holley HP book also mentions a steel needle with use of alcohol. Is this a good idea with alcohol in todays pump gas? I know buna n is no good.

Are the spring cushioned needle/seats a good idea as mentioned in the Holley HP book to dampen road shock?

Thank you

Clem made a post a few weeks ago about red and gray being the colors of Viton needles/seat.

My last Holley Renew Kit had black ones but did have the latest blue fuel bowl and metering block gaskets.

Hygrade carb kits had Viton seats since the the late 60's or early 70's. All I ever saw was black tips back then. As I remember Carter kits had brass needle and seats back then. Some customers wanted Carter only others Hygrade only and we had one that would only take American parts kits. I never told him Carter made American Parts kits. Dale
