I bought a used set of 440-1 heads several years ago with Harlan Sharp rockers and put over 300 1/4 mile passes on them with no problems. I used a small roller cam (690 lift) and ran a 8.62@155mph. The engine I am building now is a B1 with T&D rockers but my backup engine will have the 440-1 and the same Harlan Sharps. They make a very good product with excellent customer care.

I used them on my old bullet. No problems - good product.

absolutely. they're a great product from a family owned company.

My mother always told me if you can't say something nice to not say anything at all.

I run Harlands on my 440-1's.

I liked my Harland 1.7's ....

I run them on my -1 498.

I picked up a used set last year and replaced the shafts and they seem to work great!

very happy with mine!!

me to 440-1 512ci
