OK, Stocker "valve jobs".

Question here, for anyone.
How would tech check the valve incline angle during a tear down, on a canted valve type engine....or any engine , for that matter ?
I don't know, and I've never seen it done.

Is it better to do the valve job before or after you port the heads?

Level the head with deck surface up, and use an angle finder on the face of the valve. Similar to checking "things" out on a floating head type of seat and guide machine. Canted valve check would be the same process.

If you angel mill the head enough to change valve angle more than 1 degree in relation to the deck of the block deck, would you have to relocate valves guides to the 23 degree + or - 1degree to be legal in a SBC ?

Well, I guess the "proper" way to do it would be to not angle mill the head enough to get into that situation. On occasion, I have angle and flat milled a SB head to get what I need.

Will any motor benefit from a 1 or 2 degree valve angle change?
I assume you could angle mill head and install guide and seats at a angle to get as much as possible.

Thanks, Phil
With all due respect, I knew how to go about it on a Serdi or similar table.
So, in a few words, it's never gonna happen at an NHRA tear down...
Yet, if this is what this phrase means, here it is,..almost right at the top of the cylinder head paragraph.


BTW where is this spec available for various oddball engines?

It would be fun to watch them with a bubble level - "hey, it's almost touching the line, is that a thousandth?"

Always remember to level the level.
