Quick header/header gasket question (I have diffrent heads which gaskets?) help!

[91LX_5L]

I am about to buy some Felpro 1415s when I noticed the Felpro 1486's.

Now I have worlds' windsor jr heads (IRON) which have the dual bolt pattern. I have bbk headers which have single bolt pattern, mabye that is why im having troubles with them leaking? its on one side only though? Are the BBK headers fine with the dual bolt pattern on my heads?

Anyways back to the felpro question here is the link to the 1486s:
http://cgi.ebay.com/ebaymotors/ws/e...ry=33666&item=7947715496&rd=1&ssPageName=WDVW

"Port Style: Dual bolt pattern splayed port
Port Height (in): 1.400
Port Width (in): 1.400 "

Do you think those are the ones I need? Or would the regular 1415s with the stock port style be fine?

According to World's website the 1415 is the recommended gasket.

i have the same heads. the gaskets i bought that went on just solidified and cracked and leaked. now i got some stock replacement graphites and they didnt even need to be trimmed for the larger ports

Never noticed that world reccomends the 1415s! thanks!

Anyways that seems to be my problem. did you try the felpro 1415s? stock replacements as in ford gaskets? I didnt notice that any of them needed trimming? mabye thats my problem?
