5 angle valve job

[z287mgte]

Looking for the best angles that i am supposed to use to do this.

I tried multiangle vale jobs on my 7M when I had it, failed pretty quickly due to the fuel I was using (LPG) but I imagine Unleaded isn't going to be far behind.

Went back to a 3 angle job with fairly wide seats and valve recession was a thing of the past.
(was a HUGE PITA as I was running one piece shimless buckets)

Isn't 5 angle pretty much pointless? Isn't 3 angle with a radius good enough?

ok so now that i have found out that three is better...what where the angles

what are they?

Just go to the machine shop, tell them you want a 3 angle valve job with a radius on the last angle.

Ever look into +2mm oversize valves? I know the standard oversize valves are only +1mm, but is there a reason that +2mm valves like in the 2jz cant be used? I would assume the valves are too close to each other or the side of the combustion chamber?
