J head 1.88 vs 2.02

I'm building a 360 to go in my 68 dart. This will be a street machine. I have no intrest in racing it.
Stock bore and stroke, a mild Comp cam kit summit #k20-212-2, performer RPM intake and J heads,
Long tube Heddman headers and 2.5" duel exhaust.
The heads are going to the machine shop soon to have the springs and seals installed. I have this urge to
have the 1.88 intake valves replaced with 2.02. I just don't know if the added expense is worth the gain of flow.
I just want close to the same horse power the my 69 roadrunner had with its 383. I think it was rated at 335 hp. Am I going to be close without the larger valves?

With the Summit 'High Energy' Camshaft

#K20-212-2
Lift ........................ .454"/.454'
Duration ................. 268*/268"
Duration @ .050" ..... 216*/216*
LSA ........................ 110*

With a 'Street Driven' 360, you will be better off with the 1.88" Intake in the
'J' Cylinder Heads.

The 1.88" Intakes will be 'perfect' for this application.

Bigger isn't always better all the time, unless your John Holmes {*** rated **** Star}
