We sell Dart, World and genuine Chevy blocks, We do NOT sell Chinese. Our cylinder heads are PMB strike force castings that we install Manley Extreme duty exhaust valves and severe duty intakes, set up for Hyd. roller or flat tappet with 10 deg locks, ARP rocker studs and Dart adjustable guide plates., These heads are for the average boater looking for extra HP gains on a budget, and have proven to be reliable with very good HP results over the years for bolt on performance , We always recommend Cometic head gaskets and ARP fasteners with any Marine cylinder head combo . We sell all Dart and World products and always recommend the best first.

can tell you that Mike is a great stand up guy !

Regarding the Edelbrocks, I just pulled my heads to have them flow tested for an optimum cam, and he checked the valve seat radius and found them to be .006 - .009 out of round. Is this pretty normal for out of the box heads?
