I NEVER said they didnt, just never seen it before. I told you I am new to this hobby. I learn something new everyday.

But I found this here

Strange they don't show a E7 head with 2.02 valves.

Engine:
91 Roller Block, Stock Bore
Forged Pistons 10:1 These are suppose to be stock, but Ford never had a 10:1 piston in a roller motor. Where the heads milled? How do you know the compression?

Clevite "H" Bearings (Main and Rod)

I think a 58cc head will yeild about 10:1 with a stock pistons and gasket. Not 100% posistive.

The car has a digital 6 ignition box, do these not come with a soft touch rev limiter?

I think it was set around 6600 or 6800 I think not sure. I never touched it. Roushtech said it was there when we talked.

It's cause you can't fit a 2.02 valve in an E7 head....

Just looked at the picture of the valves in the first post. If they had 2.02/1.60 valves they would almost be touching.
