Hello back and welcome to the forum, hp is not a guessing game, you may have 350, 400, 450 who knows and who knows where, rpm wise that max. hp and torque really is. Only way to really know is the dyno cell. Also....and this is just a pet peeve, it's Edelbrock.

Looks like you have a mish-mash of parts, and may not have an effective combination.

High flowing heads and "Performer" don't go together. Performer is a low-speed power maker, high flow heads are for high speed power (engine speed). 2.08 intake valves are not recommended for the 4" bore. Those heads should be used on the 4 1/8" bore. We've found 2.055 intakes to be the largest effective with the smaller bore (the cylinder wall "shrouds" the intake valve).

.680" lift is nice, but what's the duration? The "@.050" numbers are far more indicative of power and RPM range. Need the LSA as well.

Heads being "angle milled" is an old-school approach to making more power with the 23 degree heads. By "rolling it over" some, the entrance to the cylinder is more efficient. It also removes volume from the chamber "quicker" than a flat mill. The practice is losing favor in recent years, mainly due to the advance in cylinder head technology making it unnecessary.

With the BG carb, this almost sounds like a "magazine build".

Get back to us with chamber volume and cam duration, and maybe we can make suggestions to "salvage" the bottom-end and much of the valve train and still make maximum power. What size headers and weight/type of car is also helpful information. ]
