A serdi job goes about 250.00, I'd rather a cutter than a stone when doing that... that's not an approach id use in this case because the existing top cut is .060 deep, being how wide these angles are...that puts the seat angle almost .100 down... I'm not sinking it more. If I get the valve proud...i can get big flow .100-.400 , not just .500+
To my knowledge there isn't a ton wrapped up in these heads, nor does there need to be...but there is some room to invest if he'd like to.
I know I could buzz through these and get 245+ can without much time....but there's more to it, I do things differently...i know.
