Im considering a set of Procomp heads #3003 for an upcoming 383 build.
Im looking at a set cnc'd to 68cc chambers. Does anyone have these heads?
The flow #s look good for the price from Skip White. A question i have is are
Rocker stud holes 7/16-14 as typical on most after market heads? Thanks

 

They're really not good cylinder heads. The flow numbers are only a small portion to cylinder head technology, and the flow numbers are flat out BAD on procomp heads.

They're cheap for a reason. If you're on a shoestring budget go buy someone else's used heads and get something good for the money spent.

 

It appears the ProComp heads are Chinese copies of the Edelbrock heads.

I've been thinking of getting a set of complete ProComp heads from Skip White, which appear to be a pretty good setup.

 

I have used pro comps before and they are not good! To start with I don't believe those flow numbers for a second. And if you do believe them look at how low the exhaust flow is compared to any other head with the same intake flow. They are just junk. They have to use big crazy cams to make any power.
Save up a few more dollars and get a set of profilers. They are around $1050 shipped.
195 cc's if you going to 6500 rpm or 210 if your going to 7000 rpm

Their flow numbers are garbage. Their 210cc intake heads flow worse than many good 180cc heads.

 

Thanks Guys.....im taking your advice...it was between SHP200, Brodix IK200,and Pro Filer 176 series 195's.......the Pro Filers won out with a little better numbers and i believe better velosity..... $1138 to my door set up for a hdy roller.
Thanks again

I would stop thinking about it unless you want to make crap for power.

 

Hey Pete - know anything about these guys?

AFD, down your way. New local design sbc heads apparently.

 

The only flow spec they have is at 650 lift. That is a worthless number

 

Could be a decent new head could be junk

As said peak # doesnt mean anything most just use it to sell heads as everyone foams at the mouth over peak # and just dont know any better.

Might try posting about those heads on speedtalk guarantee someone there has had thier hands on a set.

 

Yeah, I had a bit of a poke around a couple of local (Australian) forums several months ago, from what limited anecdotes I found, they get an ok rap from the Ford guys, at least for racing. They've only moved to an sbc offering recently afaik, and as noted above there's scant info on that ebay listing, or on their site.

Price is much better for us over here tho, for any decent aftermaket set from any mfg (ie anything better than Procomp) you're looking at $2k - $4k a set.
