[Alpines] [Tigers] 289 heads

[Tony Somebody]

I have 2 sets of 1965 heads- my machinist, now retired and a Ford man said the 65 heads had a higher nickle content , making them stronger. he replaced the seats and valve guides- the seats for unleaded fuel, he then used Chevy valves. There is just barley room for them both to close. I haven't ported either set and actually he only built one set, another Tiger owner from the north east area sold me several of his spare parts and he had a set of 289 heads already built exactly like mine. I am running those on a 289 and yes, there is a major difference BUT now I would invest in a set of aluminum heads as opposed to paying the machinist for his time. Luckily for me, when I had the heads built, labor wasn't so expensive and as I mentioned, me machinist was a Ford person thru and thru and enjoyed helping build a go fast Ford engine. If you are going to keep your 260 or go to 289 heads you can increase the size of the valves- depending on the cc of the head.
 I also highly recommend porting and polishing and if you don't have the patience, the professionals don't charge a ton. I spent $100 on my S5, 1725 head and the work was wonderful BUT that's in southern IL. I'm sure things cost more on the left coast.
Hope this helps some.
TOO, congrats to "would you believe" for finding his loose bolt- sure did have the list working hard solving that problem. Next time I bet someone ask if everything has been rechecked for torque.
Cheers,
