I have a set of World Product Torquer S\R's with 76 CC and was wanting to mill the heads to acheive a little higher compression.

So my questions (please excuse me if they are dumb), is:

1- Can I mill (actually the machine shop) the heads so they are around 64CC??

2- Do the heads need completely disassembled to do this??? I would prefer not to do this as then are new.

3- Any rough idea on costs?
I would call the shop and ask, but kinda want to get an idea before I talk to them.

Thanks

Going down more than about 8cc, the
milling should be angle-milled to correct
the geometries.. Angle milling is about
$150 around here. You may need new
pushrods at that amount also??

The heads would have to be dissassembled.
No major hassle there...

You'd also need to have the intake manifold milled to ensure it will seal properly with the milled heads.

 

Not if the heads are angle milled....
