Which head should I use?
 

I'd like to hear from you BBC racers, I'm building a 427 L88 Stock Eliminator car and I'm trying to decide which head to run, the 077 head
or the new 401 head,any knowledge or experiences with these heads that you would share with me will be greatly appreciated.

Thanks,

Richard

the 401 is the only legal head in NHRA

Are you sure about that? Thought the 077 was an original OEM #...anyway all I've used is the 401

Re: Which head should I use?
 

According to NHRA 074,077,and 401 are legal for the 427-430 H.P. (L88) engine 1969.:)

Use the 401 head.

Dwight, can you give me a reason to use the 401?

Re: Which head should I use?
 

There are several reasons to use the 401. Availability, cost, condition, and performance are a few.

What Alan said. Port design, combustion chamber, durability. You can sell 077 heads as collector items for more than 401 heads cost and the 401 heads make more hp.

What everyone is saying is that the 401s are not exact copies of the originals. Use them if want to get the most for your money.
