Flat tops ey? I'm too lazy to pull my head off to have a look Smile I know they have valve recesses, but I always thought the pistons had a little peak/crown on them too.

Here's a few bits of interesting info from www.alldata.com (regarding automotive recalls and technical bulletins) this applies to the 1986-1989 Toyota Celica ST162s

ENG028 SEP 90 Engine - Piston Modification Due to Knock When Cold

ENG018 SEP 90 Engine - Cylinder Block and Crankshaft Modified

ENG019 MAY 88 Engine - New Piston Ring Reduces Oil Consumption

032032787 MAR 87 Engine - Bearing Cap Redesign Reduces Vibration

02611687 JAN 87 Engine - Oil Pump Gasket Improved

ENG005 JUN 87 EGR - Pipe Flange Gasket Improved

SUSP005 JAN 90 Alignment - Camber Adjusting Mechanism Discontinued

How much does that suck? I want camber adjusting mechanism Very Happy

However, it doesn't say anything about them using different heads between years or anything about them changing the cylinder head design. Unfortunately all that stuff up there only applies to american delivered cars (I think) so who knows what's going on elsewhere in the world Razz But they obviously had to change a few things over the years to fix up some niggles here and there, so maybe diff. pistons etc is part of the deal...
