Default d20e-a heads

need to know how the d20e heads rank up against the d0ve-c and the d00e-r heads. what ones are better for the money? i can get a set of d2s for 975 all assembled ready to run or should i just wait to find some d00e-r or just get new stuff put into my d0ves?

In my opinion the D2 PI head is right in between a DOVE and a DOOE a good middle of the road head.

X2 ... in my opinion, probably the best overall OEM production street head for a big block. It simply has a larger combustion chamber than the other heads which were mentioned.

More than the production "retainer to seal" clearance will allow. They will coil bind around .575".

These heads are more common than the D0OE-R heads yet some people still think them rare and mistakenly ask as much for them as a set of iron CJs. If the D2OEs that you are looking at for $975 are "assembled and ready to run" with decent new springs, valves, and machine work, then I'd think that is a very good deal.

If you want to run that 0.634" roller cam then make certain the necessary machining has been done on the valve train side of the castings.

I priced around some before I bought mine to see if the guy was tring to screw me. Around 400 bux for a bare virgin set is about the norm, I got mine for 300.

I use stock production length valves with .250" instead of .350" tip length.

I am pretty sure that .001" is a mistake.

Where are you located? Last time I talked to Al Moody, he had a set of DOOE heads for sale for a grand. Don't hold me to it, but I think he said they flowed in the 370 range. Been a while though.

The PI castings are capable performers when ported correctly. They suffer from the same lame exhaust port architecture that the rest of the BBF lineup does.

Do not expect big HP with OEM unmodified castings. What you should do with them depends on intended use just as the Doves we discussed on the phone. Even those BT heads needed intake port work...
