Hi all !
Haven't been on here in a good long while but need some advice from the 426 Hemi owners/builders here..

My brother is again working on getting his original 426 street hemi back together which is in his 1970 Hemicuda.
He wants to pick an aluminum head that has the stock valve sizes and location and has quality machine work as in a no issue mate to his factory intake manifold
sealing surfaces. Block and intake manifold is as factory cut no milling.

This will be a street application with 10 or 10.5 compression with a hyd. camshaft one or two steps over the stock grind.
Haven't decided whether to go hyd. roller or flat tappet...but I like the hyd. rollers.

So what about the new Edelbrock heads or Indy? From what he told me some of the Edelbrock Hemi heads have the exhaust valve moved over
and a modified valve relief would be needed.

Appreciate any info. Thanks!
