Guys I have always thought conventional meant CONVENTIONAL valve angle.
Since when did a 15* small block ford head become conventional??

 

[outlaw68]

Sonny its NOT!
15* valve angle VS 20 valve angle.
Most if not all give a weight break to the standard small block heads. IE: 23* chevy. 20* ford, 18* mopar.

The victor head is a inline head, not conventional.

 

[Malibeast]

That victor head is a conventional head..??

 

[christiandseller]

The victor head is a inline head, not conventional.

I thought an inline head was a conventional meaning non canted,wedge style head.

 

[JOHN BRADY]

So is an 18* or 15* or 11* or 9* Chevy head conventional also?

 

[sickboystang]

so a 170cc Twisted Wedge is non-conventional?

 

[Paulie9fingers]

That "conventional" word is a royal pain in the ass. I think that the 15* Victor is conventional because it is still an inline head, I also think the Chevy heads listed above are too. As stated above, the "factory" valve angle heads generally get a break over the other "conventional" heads and they should. The twisted wedge, Yates and SB2's are not conventional.

. . . just my 2 cents

CONVENTIONAL, no different than angle milling stock heads, inline just like O.E.M. heads

totally agree

 

[sickboystang]

totally agree

sooooo....take a weight penalty for 170cc TW heads, or swap to a TEA 255cc Highport and take a weight break?!
okay!

 

[cmccarthy]

Most sanctioning bodies around here give Twisted Wedge heads a pass because they aren't any better than a top shelf inline head. Regarding Fords, the Yates/Cleveland type stuff is what is usually considered an "unconventional" head.

I know, same here.
I just think its a bogus argument, valve angle leaves alot on the table as far as taking or adding weight. I just like to hear peoples reasoning for saying a 20* head is at such a disadvantage. You can go back to the old Holley Systemax heads that were I believe 15* or 18* heads and yet they cant hold a candle to a max effort H-P or Kuntz Track1

Agree with Charles. Conventional is determined by valve layout BUT +/- 2-3 degrees from factory spec is also usually stipulated for legality.

 

[vrtical]

this is entertaining.

 

[lsxcoupe]

i agree on the valve angle change adding or subtracting weight but this head being an inline head makes it a conventional head.....IMO

SO lets go one step more.

So a Stock BBC head is a canted valve head, and so is a big chief. Why is the Big chief not a conventional head?
