Last time I ran a comp dual energy 275.
At this point there were no valve reliefs in the pistons.
A friend of mine rebuild my new 727, but at the first kick down the trans don't shift, so I spin to 7000rpm.
The hydr. valve train collaps and now little notches are in the pistons.
For the new cam and head set up, I will put on the heads with an home build valve cutting tool.
