atto666 Member 35 Member For: 18y 2m 22d Gender: Male Location: liverpool, sydney Posted 04/07/11 02:05 AM Share Posted 04/07/11 02:05 AM OK, I am going to ask what is most likely a stupid question that undoubtedly will be met with differing opinions. this is what forums are for.I have a BA T with a blown head Gasket. I have a spare non turbo head.What are the differences between non turbo and turbo specific cylinder heads on BA's. They are listed as having differing part numbers.My plans are to get the non turbo head ported, polished, machined and what not, so I can removed the old head, change the gasket and fit the machined head,and be on my merry way, without having the car apart for a week or so while the head work gets done.So, what is the difference?, and, if anyone has even more knowledge, can it/should it be done???Dave Link to comment https://www.fordxr6turbo.com/forum/topic/75641-cylinder-heads/ Share on other sites More sharing options...

Assuming the head is machined to suit the valves there shouldnt be any reason why they cant be used.
