Hi, Looking for help as trying to build 1st cosworth engine for my mk1 escrot (mexico). I have got the following bits:

yb 2wd cylinder head with std cams, not been skimmed.
205 pinto block,
escort cosworth pistons,
twin 45 DHLA carbs.

The last means idealy I want N/A.
Is their anything special I need to consider for the conrods and crank I will need?

Can I skim the head down sufficiantly to get about 12:1 c/r. will I need to put valve cuts in the pistons?

Would love 250bhp, happy at 200

Trying to do on absolute budget!
