B1 intake bolt pattern Question

is the intake bolt pattern the same for the B1 original heads and the B1 MC heads or are they different like the TS heads?
looking to try a intake swap.thanks

same

Yep, I just got off the Phone W/ Scott and said they are the same but you may need intake risers depending on the application.


The TS heads have a different bolt pattern though.

SO MY NEXT QUESTION IS,
ARE THE INTAKE PORTS the same on both heads.
best machine made me a set of intake adapter plates to put a indy 440-25 crossram on a set of b1 original heads, but looking to put these adapter plates on some b1-mc heads and use the adapter plates to match up the indy intake for dual carb setup to the mc heads. i'm still learning these B1 head configurations.
thanks wildbill and steve G.

Port location is the same for both heads.

what do they look like I have a b1 and was looking at how I could do it how much did it cost

You have to port match the spacers to the intake and the head. The spacers are not a bolt on deal.

IS this a low deck or tall deck one i have is a low deck 468 so i would not have as much space as a tall deck that would be a big angle to match
