I'm making a valve spring compressor tool right now and I need a dimension.

What is the angle between the valve stem and the top of the block (bottom face of the cylinder head) ?

Or even better, what is the angle between the rocker pedestal seats and the valve stems?

It looks to be about 19° for the first dimension, or 17° for the second dimension.

Anyone know? Thanks in advance.

And what diameter / thread are the rocker bolts?

How about the valve cover bolts?

FASTONE

The valve angle to the deck is 15 degrees,don"t know about the stud? the valve cover bolts are 6 mm.

thanks - we milled it at 15° Although the rocker pedestal seats seem off by a little bit, this is close enough.


I'll post pics of the tool tomorrow. Then taking orders next week
