My bare Performer RPM heads will be here shortly so I’m starting to put together a parts list.
The question of the moment is my valve choice. I have found three options in the 11/32” size.
Edelbrock - $139
Hughes - $105
440 Source - $80
Is there any difference here? They all say 21-4N stainless.
Any other options?
Seems like going with the Hughes or 440 would be the thing to do.
Opinions?
I’m going to have my local machine shop do some port work on the heads to clean them up and get more low and mid cycle air flow.
I will also be going with a Comp XE285HL cam and their recommended Comp springs. If that matters.
