Precison Race Components Small Runner UPDATE!! I thought I'd jump on ls1tech & thow out a quick post on the status of our small runner cylinder head! The new small runner head is nearly done & I'm completely happy with it! Here's a few quick specs on the new head!
Built with a Edelbrock casting!
202cc runner!!
62cc chamber
2.04 intake valve
your choice of exhaust valve size!
PRC double spring kit good to .660 lift!
A SMALL RUNNER HEAD THAT DOESN'T BACKUP @ .60!!!
I'll get flow data up for you guys in the next few days! The runner flows about 315cfm @.650" & moves awesome air throughout the flow range!
Retail pricing should be about $1900!!
With this cylinder head you'll get:
The smallest runner available!
Big peak & mid lift air flow
.660" lift springs standard
Decked & Assembled to your specs with your choice of valve sizes!
62cc chambers standard OUT OF THE BOX
I think we've put together the ultimate small runner head available! Look for pics & flow data in the very near future!

The thing that's really cool about this head is it doesn't fall flat on it's face like the competitions small runner stuff! I have a few different valve configurations that flow past .700"!!
Look for engine dyno tests very soon!

You guys are really doing a lot of R&D!! First the MS4 now this head, this is good for us LS1Tech folks. How does it stack up against the 205 runner heads? Any comparison? Would this be a good choice head for the Torquer V2?

i still say it's the cross section of the port that determines velocity,more than port volume.but the heads sound like a great deal,and should put down good numbers....keep up the good work guys

The chambers have to be CNC machined on all the porters version head. There is a ton of extra material everywhere in these heads and start off with the tiniest runners/chambers I've ever seen before. But, I myself don't know -all- the tech stuff on these heads... I'll let Jason know there are some questions in here and have him respond when he gets caught up.
