What "extra work" to install TFS heads

XR1 did an excellent job of describing what it takes to put heads on an SN 95. When I put the GT40 X's on my 94 I ran in to the same problems, my solution was a little different.

I used the 87-93 cast valve covers. I had to grind a very small portion of the valve cover to get the alternator to bolt on. I left the EGR on at the time and just ground a flat spot on the bottom of it where it was hitting. I had to grind the the boss on the TB adapter as well. I later removed the EGR and made a block off plate.

You will need new head bolts as the factory ones are torque-to-yield. PV clearance should always be checked, but if you are going to use your stock cam I wouldnt feel bad about letting that pass.

Good Luck
