[DeTomaso] CHI 4V heads question

[Mike Drew]

Larry,

I wound up using a pair of Remflex gaskets on each side (collector gaskets) for that reason. I think it came about when switched from iron to CHI 4V heads. 

That solution worked fine for me.  They have a lot of ‘crush’ capability and can be useful for alleviating such concerns. I also use their header gaskets exclusively.

With the mufflers as close to the body as possible, there is a gap at the top of the header flanges of about 3 sixteenths of an inch. Even removing the ZF side mounts and letting the transaxle rest on the rear crossmember, there is still a header flange gap.
