I cant even begin to explain how passionate I am about valvetrain compatibility and integration. People wonder why I'm so pig headed about the components I will reccomend or fit to cylinder heads 😁. There is a good reason... Here's one of the best written well explained articles I've ever seen on the subject. Its insightful and informative. It doesn't go into too much tech detail, but doesnt need to either, as all of this cam and valvetrain technology (and more) is what we do at HPHeads and is directly available to our customers. ...

New product development while in lock down! This carburetor spacer has been on the to do list for a fair while, so its great to find some time to get it done. It is designed specifically to fit the shape or our Toyota V8 intake manifolds. A few finishing touches and then we will make a run of them.

If you aren't running one already, we have plenty of manifolds in stock for the 20/21 racing season.

Some engine builders have been cutting and welding our vvti manifolds and fitting them to Nissan VH and VK motors with great success. So although the demand is low, the result is worth us casting manifolds for Nissan Superstock engines. I doubt they will be ready for the coming season, but you never know...

Last of all, Good luck to everyone out there, this is a very testing time. Lets be patient and support those in our circles. ... See MoreSee Less
