bin in touch with a company in doncaster www.edenperformance.co.uk
and they told me they can do me a 2.1zvh bottom end 4 1100 which i think is cheap.
but they told me i need to have my head welded to fit the bootom end (my frst head) (which is extra obversiouly). how ture is this cos i never heard of this before.
also they said :-
The head gaskets we use are genuine factory ford 4 layer steel items which can handle over 400bhp.
how can a standard gasket take this much stick. aslo i want to run bout 18-20psi so is the c/r 8-2-1. gunner handle this also will the head gasket.

help will be much apprciated
