So, I mentioned them in several other threads already. Anyway, Edelbrock recently released a new head they call the Pro Port CNC, which is a fully CNC'd next generation version of the already formidable RPM heads. 2 sizes, 170cc intak port and 190cc. The 190 head actually outflows their Victor Jr race head, which has a 210cc intake port, and flows the same as CHI's 185cc port canted valve "3V" head.

Well, they just released flowdata for the smaller 170cc head targeted at 289/302/302 strokers. With a 170cc intake port, this head OUTFLOWS the potent AFR 185. THAT is impressive. In all liklihood this head could make for a 450hp n/a 302 that has excellent street manners, perhaps more. The 170 Pro Port handily outflows the AFR 185 on intake and exhaust up to around .500 lift, where the AFR 185 wins out on intake flow, but the 170 head still outflows the AFR on the exhaust side. You'd need to get the AFR nitrous/blower exhaust port upgrade to beat the exhaust flow of the 170 head.

p/n 51309 is the 190 head and 51319 is the 170 head.

The 170 head also is using a 1.94 valve and not a 2.02 valve.

Any price on these yet? I can't find much about the 170's online.

good post!

I've only seen a few places list them online, but they all say call for pricing, new item etc. I imagine that they're manufactured on the equipment they already have, so they can't be too much more than the current RPM heads are. They're actually offered as an option in the top end packages on their site. Either head will be capable of making monster power though. They need to make a larger version, with 210+cc intake ports, for the 351 stroker apps that turn more r's.

thats the victor jr. head. i beleive it has 210cc intake. there not too bad either on summit there 679.50 each assembled. you can also go bigger- the victor series head. there like 225cc intake to 276cc intake. there rough cast though so youd hafts port everything it says. those are like 570 each NOT assembled

so who will be the guinea pig here!! and buy a set and let us know how they perform???

If I had the money I'd put a pair of those 170 heads on my 302 right now. Edelbrock does not make bad heads at all, their "old" RPM heads were on par with the AFR 165's in terms of making power, with about the same port size. The new head still has the same port size, but flows substantially more.

And I meant they need to make a Pro Port version of the Vic Jr. As it stands now the Pro Port 190 heads outflow the 210 port Vic Jr heads, so what would be the point of even getting a Vic Jr head? Thr 190 flows more an has higher velocity. Though, the Vic Jr flows a bit more at higher lifts, like the .600-.700 range, so I suppose it would work better than the 190's if you have a high lift cam with a lot of duration.

i'll be a test dummy, but who's paying for these?
