Jim/Woodz428:

Jim, you wrote: "Sorry, forgot to add the firing order:
1-3-7-2-6-5-4-8
(Number 1 cylinder is front, on right from drivers pov)"

The #1 piston on a Cleveland is on the right/drivers side?

This would be totally contrary to my 427 in which #1-4 is on the left/Passenger side.

Woodz428,

He has taken into account pre-load with the lifters. The problem goes back to compression on those cylinders and until just now I hadn't thought of just havinghim remove the rocker arms on 1-4 and then check compression - and here I thought I had thought of everything - stupid me!

Thanks guys!
