4k help

[Ice block]

for all you 4k experts out there .

Feels like shes under heaps of load when starting , hardly turn over . Tried new starter motors and battery .
Rebuilt this year by me .
Just wouldn't go one day . starter motor clicked in but wouldn't turn . Towed started alright .
Now has no manifolds and nothing connected , Feels like in has heaps of compression in it , Turns over fine with no spark plugs , i've checked vavle clearances and that all timing seems ok . But has heaps of compression .
and ideas much appreciated .
