FORD GT40P heads GT 40 P

Mustang Explorer 40P Cylinder Heads GT40 P for Sale (SOLD!)

SOLD! Check out the finished product!

These heads had all the quality detail and attention I could possibly attain as
I built them for my 100,000 mile daily driver engine that would survive blasts down the 1/4 or 1/8 mile in my 302 cubic inch 9.81:1 compression ratio long rod engine I had planned.

There is not a thing wrong with the heads or any of the parts in any way

I planned them and had them worked on to perfection.  But NEVER used them or completely assembled them.
In the process of deciding on a camshaft, I decided against a dual-purpose car instead will keep my daily driver totally stock as it is and will build a much more wild car for strip use at a later date.
My changes = your gain... you don’t have to invest the hundreds of hours and expense I did getting the absolute premium parts and machine work that is available.

 

Hardened seats installed on exhaust

• 5 angle exhaust
  1.554” high quality stainless steel swirl polished undercut exhaust valve (with an extra fat margin) by Manley
• 3 angle intake
  1.95 high quality stainless steel swirl polished undercut intake valve by Manley

I made sure that these valves had the same stem height (unlike the OEM hardware) so the same exact springs and valve retainer, can be used on intake and exhaust! in fact...

• Brand new never used titanium retainers included
• *New phosphor bronze guide liners*... not the "quick install" these solid units required serious machining have been perfectly fitted to the valves.  These will outlast the stock configuration and are superior in every way.
• Brand new keepers included
• Rocker pedestals machined down for guide plates
• Brand new valve stem seals included
• Brand new never used Manley guide plates included #42152-8 (5/16” pushrod) (fat 7/16” stud)
• brand new never used ARP rocker arm studs included #134-7103 (fat 7/16” stud)

spring seats NOT machined: this means you get to choose the exact spring type and pressure because I did not have any work done on the spring seat or material removed (because I never choose my cam/springs)

• sand blasted
• pressure tested
• leak tested
• magnafluxed
• before the machine work was done
• heads both milled down to true the deck
• combustion chambers polished
• Rocker pedestals machined down for guide plates(5/16” pushrod) (fat 7/16” stud)

 

Everything possible good was done... no porting no spring seat machine means that you don’t have to worry about those things being done not to your liking or application.
