How much can you mill TFS TW?

Skyman · 05-12-2002, 06:04 PM

I just pulled off my TFS TW, and one of the heads are slightly warped.

I was going to just have them surfaced, but if I mill them for a little extra compression whats the max they can be milled?

They have that big 2.02" intake valve so it cant go too far.

If I mill them .030 or .040 what if I need to surface them again in the future? Am I going to have enough head left to do it?

Also if I mill them .030 or .040 how much do I need to have the intake milled?

Or should I just have them surfaced?

Thanks

I have my tw heads milled .030 and I didn't have to get intake milled but any more and I would have had it milled. So I can say more than .030 get the Intake cut to match the heads and also check you Piston to Valve clearance.
