Edelbrock rpm alum heads & hp exhaust manifolds

[s5757s]

The big block 440 edelbrock rpm aluminum cylinder heads p/n 60189 i want to use have angled spark plugs.

Can i still use the 73-74 hp cast exhaust manifolds that i already have ?

Thanks

Is there any specific reason you would want to ? Why not go with headers for optimal performance from the motor and heads? The hp manifolds won't give you the performance that a really good set of full headers will,not even close.

i don't think #6 and #8 plugs will fit the manifolds. edelbrock makes a straight plug head for mopar performance that will work.

Honestly, i think that would look like a$$. If anything, get the 440 source heads, grind off that huge parting line on the front of them, paint them engine color, and bolt on your manifolds.
