I have a 239 block # EBV-6015-0 (hard to read)...with CF stamp
heads are # EBV-6090-A
I bought a Fel-Pro gasket set for the 54 239 with the metal head gaskets...
The new gaskets do not have some of the port openings cut out like the old gaskets have....
Should I look into another head gasket set or should I take a dremmel and open up the cut-outs in the new gaskets that corrospond with common openings in the block and head???
It seems to me that the water openings in the gaskets do not have the same size openings as the block/heads. I think the holes in question are the kidney shaped openings near the front of the heads/block. In theory, by reducing the flow through the front openings, you get increased flow to the rear of the heads. I've been lead to believe that it's done like this on purpose and not to enlarge the openings in the gaskets.
That's my story and I'm sticking to it. ;-)

Terry's (Overkill) is right; this was a big discussion on several flathead forums. This was a major change on 8BA's vs the 59AB's and other earlier engines. FelPro and Victor gaskets sets (current production) are different than they used to be, and when you buy FelPro, you get Victor head gaskets (or is it vice versa?) because the demand doesn't warrant both of them making them. There are some differences that look suspicious, but they seem to work fine. Just make sure you get the left and right gaskets on their respective cylinder banks!
Heads are being machined as I write...so I'll put them on soon.
What has everyone found to be the best result in sealing these metal gaskets on these old blocks ....I have usually used a spray copper on both side??? Any other way work well? thanks, Ed
