[Tigers] 289 heads

[Ron Fraser]

Tom
	The 289 was first cast in Dec 1962, the 6 Bolt 289 started in Aug
1964.  The intake valve was increased to 1.78" Feb 1964.   The small valve
heads were produced from Dec 1962 to Jan 1964 and would all be on 5 Bolt 289
engines.

	You would need to go through all the casting numbers and date codes
to understand what parts you have on your 289.

Ron,

  Off hand would you know if the 289 heads with the smaller valves came
exclusive with the 5 bolt 289? That is what a previous owner transplanted
into my Tiger.  My Tiger seems to be a hodge-podge of someone's spare parts
.  Thus, while I could have anything on that motor, curiosity has me
wondering (though I do recollect with fuzzy-ness something designating my
heads as 1966 vintage).

So, until I can remove all the stuff my wife and kids have piled on the car,

find a place to place the un-hinged hood and wrangle the not so easy to
remove aluminum "Powered By Ford" valve cover ..... .

Dave,
 My understanding was that the Ford small block heads in general never
flowed very well. It is just a guess, but unless the compression changes,
the larger ports and valves of the 289 likely make little different to
remove low and mid range torque on a 260.
