on my 1406 eddy the left (pass) front nipple is ported. Superformance (on here & good guy to deal with) has .015 thin BB side gaskets. I'm a believer in the gaskets + cement (permatex 99MA "high tack" the red spray stuff in the can) tho many do without but if the height of the bolt holes in the V will allow the use of em then I definitely would suggest going that way
