5 angle valve job? Can anyone explain the beneftis of a 5 angle valve job on the intake side of some 243's. Brett at Land Speed offers a 5 angle race valve job on his stage 2 and 3 243/799 heads. Is that common? I've heard of 3 angle valve jobs, but not 5.
A good valvejob is more about the angles than the number of angles. The extra angles are typically both under the bottom cut, and the number of angles doesn't necessarily make it only for a street application or race application. That would be more of a result of the angles themselves.

Good info there. Thank you. Do you know the number of angles the typical 243/799 head porters do; i.e. AI, TEA, TSP, etc.?

Also, exhaust valvejobs can have twice as many angles as the intake in some cases.

It doesn't really matter the number of angles as much as the angles themselves! And you rarely, if ever, see or hear any head porter share their data.
