which cosworth head to use?
As title i am currently getting the parts together to build my engine and have the following 2 head options available:
1 2wd (3dr) head measuring 138.8mm with no corrosion at all in the waterways but does need a repair to the thermostat housing threads
2 4x4 head measuring 138.6mm however this does have some slight corrosion in the waterways.
Will be going onto a 200 block standard comp using group A gasket and standard bolts. planning to be running P8 wasted spark 55lb blacks and a t34 55 housing.
Whichever one i end up using will get new guides etc, just wondered on peoples thought and why.

Reason: incorrect 2wd head height
