Hey guys educate me on KRE high ports? Would they be a good option for a 4" stroke street/strip motor? Can they use ARP bolts or must they use studs? Will they work with RPM intake or other Q-jet compatible intake? Can they use stock guideplates, typical roller rockers, etc? What does it cost to build a set with valves, springs, etc?

How much HP are you looking to make first off?

Those heads will not work with a out of the box rpm manifold and a 750 Q jet Carb will be a restriction in and of itself on a 428 or larger motor above 5400 rpm with theses heads dependant on how it's Camed.



The flow level of the out of the box heads will overwhelm that rpm Intake manifold and even worse the limiting HP factor of that it will narrow up on the motors power band and make that band more peaky!
A Victor or similar Intake is the only way to go, and to use such the car needs the gearing for it, and once your into the Victor manifold your Q jet can not be used .

You did not post much info, but I think your looking to bolt on way too much head for the way your car is set up right now to make full use of it
Also if you have D port headers now your into a real good chunk of money stepping into the needed round ports!

Chiphead, I believe they would be a great head for a 4" stroke street/strip motor. If one is using round port headers anyway, Highports are the most versatile head out there. If you order new from Kauffman you can get smaller intakes and exhaust valves in these heads for a smaller cube engine. I had them do a set with 2.075 intakes and 1.625 exhausts. They still flowed 317 and 202 @ .700 with good velocity in the port. These were bolted to a +0.30 389 cubic inch pump gas motor. I did use a victor on this combo, but the northwind intake is available now and more suited to these heads in stock form.

I think they are a great head. Only drawback is the coolant crossover does not align with the timing chain cover. Plugging the coolant holes is the only cure.

Some of the SS racers still use a Qjet with a Victor. GTO Karl here used one on his street car and a Qjet had a nice adapter he made.

Hello all,I have a 4" stroke & 4.210 bore engine,do you think an original Nash intake will work ? Also what size valves would you order using a single pattern solid roller with 270 at .050 and .420 lobe lift. Thanks

How much power did that make?

If you want to use an RPM and Q-Jet maybe you should consider KRE d ports rather than the HP's
