Are the slotted water holes OK in the Fel-Pro 1039(see pic)? Much more restrictive compared to the other gasket.
I'm building an aluminum headed 10:1 Hemi street motor (4.500 bore). I have these 1039's and the brown gaskets pictured (no p/n's on them). Anybody know the brand / part number on the brown ones? They're about .050 un-compressed.
Also, will the 1039's brinnell my heads? I like Fel-Pros in general, but would like to go thinner than .051 compressed and don't want the brinelling.
Any help is appreciated.
