I am running GT40 heads, don't know if they are the "p" model. No problem
with the header fit, and stock valve covers work so you can keep a stock
looking engine with them. They come painted black, so I painted them blue
to match stock color.
But, you probably cannot install them unless you are also rebuilding your
block.
1) The coolant passages on the heads do NOT match the block. I was
rebuilding the block anyway, so I just had the shop drill holes in the block
to match the coolant passage locations in the heads. I have a 5 bolt 289
block.
2) Valves are really big, don't remember exact size. But, with any
reasonable pistons the valves are not going to clear the pistons, so it
takes some work to notch out the piston heads to clear the valves.

Subject: gt40p heads
I do have a new set of gt40p heads and had planed on using them on my Tiger
at
some future date- most recently considering installing them on my Alger. I
know the plug angle isnt the same as a 65" 289 head and am concerned about
fitting headers or even stock exhaust manifolds BUT want headers naturally.
Is
anyone running the gt40p heads? Is it a known fact they will not work on a
stock Tiger?
