Anything special about Lightning heads?

Is there anything different or special about Lightning heads and cams,
or are they same as any other PI heads & cams?

94 SC/auto.

Hey Chris..how you been?
The Lightning heads and cams are the exact same as the other modulars with PI heads.
The only change made to the Lightning 5.4L was the OE install of forged pistons-they even use the weakling powdered metal rods.That,and of course-the SC setup

Hi JL, good to SCee you too.
Doing allright,
though i'm still working a couple cylinders short,
what with the 3.8 SC still. ;-)
Thats right, still no Mod cars here, yet,
but i saw some Lightning heads FS and got curious,
thought they might have unique cams or something
worthy of buying for resale to ModSquad buddies.

Since i decided not to mess with it, here's a Link
for whoever could use PIs.

94 SC/auto.

I have a set of Lightening heads if someone is interested. I bought them for my PI swap, but didnt end using them because I didnt want the higher compression.

so those heads right there would be the same as doing PI head swap but have a higher compression then PI?

I think what he's saying is;
Any PI head swap will result in higher compression
than your non-PI heads;
and he decided this was not particularly
a good time to start buying premium fuel.

SC is correct. Stepping up to the 10 to 10.5 compression on a engine that had 100k on it to me was a bad idea. Not that it couldn't handle it, but I want mine for the long haul and decided to stick around 9.5. Not drag queen(dresses just don't look good with my legs), so it wasn't needed. Hence the 3.27 rear end still.

The compression is the same, they are both PI heads.
