3 Angle Vavle job verse 5 Angle?

[JEEP DRIVER]

What the deffernce between a 3 angle Vavle job verse a 5 Angle?

[IH 392]

Two angles.
The standard 3 angle seat has the 45* seat with a 30* top and a 60* bottom, a five angle ads a 15* on top of the 30* and a 70* under the 60*, the valves themselves may have multiple angles cut on them also.
A 5 angle valve seat is unnecessary until about 7000 RPM's .

IH392, Ok thanks makes sense; Yeah I was Looking at the Titan Monster 4.9 And I notice that it said that on the Cyl.Head they did 5 Angle Vavle job I was very curious about that......does that typically make more hp went you go with a 5 angle verse a 3 Angle.

[4.whoa]

It helps flow, but it's not all that necessary for these................WHY are you looking @ titan????????????? It seems like everyone that has had one regretted it

LOL....Don't worry I Don't plan to buy one, I like the Idea of building my own "stroker" (Mainly because I know what I put into it) Hopefully in the near future I will get the chance to built mine. But there claim's are interesting to say the least, I was just curious about the 5 angle valve job, it made me wounder if that was a big factor in helping them reach there 315 hp claim.
