Your Ford C 460 heads?, .. bronze seats, ti valves and 55* seats
I would think will help if they don't have them.

We do free evaluations if you want us to look at them, .. call Jim 10am to 5pm at the shop

Visual and measurement, .. check guide clearance, seat run out,
deck flatness, visual and measurement inspection of porting,
.. flow test is $75 but if you get work done it's free.
