The heads are great. Intake is fine.What are the specs on that cam? If you have stock rods you need to keep your revs around 6000. Stock rods sometimes would rather be outside other than inside the block for some reason at that rpm. I'd say in the 11's just guessing.

the cam is #35-254-4 duration @.050 In.250 Ex.256 lift In.554 Ex.558 lobe sep.angle 110º RPM range 2800 - 7000....
the engine has the stock rods but ARP bolts.
any tips for the car?

Your base timing is alittle low,I would bump that up closer to 16* and also have it bring in full advance faster.

As long as thous plugs work you can use them,but if they dont try a NGK FR5 gapped to .45

What kind of converter do you have?

How hard is the car launching, what stall do you have, I would use the NGK also, maybe bring the gap in a little.Is the engine tuned?? How does the car run down the track now? does it pull hard start to finish ??
