Version 1/2 race spec ported and polished heads with incol valves, piper 276 cams
For sale are my race spec, ported and polished v1/2 heads for Subaru Impreza.
They were sent off to autosportif who specialise in Subaru rally car engine builds.
At great expense they skimmed the heads, ported and polished. Completely rebuilt them with all brand new parts. This included
Hydraulic lifters swapped for solid lifters
All valves replaced with Inconel valves all lapped in place
Uprated springs and retainers
Then some brand new cams were bought, and sent straight to piper, who reprofiled them to 276 degrees.
This lot cost a fortune, and will support a 800bhp engine setup.
The head work was just over £2k, plus the price of the head, plus then £900 for cams and reprofiling.
This is mind I'm listing them for a bargain price, as there a bit overkill for my 400bhp build
£1700 reduced £1500 no offers

I've had mixed answers everytime ive asked. Most people seem to think they will fit v1-4. But I cannot say for sure. But they are the origional heads from my Wrx ra v1, which have then been sent away for this awesome rebuild.
V5 on they will fit but you will need some custom work to make them work as the inlet manifolds are different
