well i know the afr 165's use a 1.9 intake and a 1.6 exhaust. and i believe either edelbrock or trick flow uses a 1.95 intake so you shouldnt have any issues there. lift and duration will effect p/v clearance tho.

well lets see here, i wana grab a #19 steeda cam and 1.7s...
specs on the steeda: (This is for the No,18 the 19 is supposed to have the same specs)
[ul][*] Lift .480 w/1.6 Rockers[*]Duration 220° @ 0.050 intake[*] Duration 226° @ 0.050 exhaust[*]Lobe Separation 112[/ul]Think Ill have a problem?

Twisted Wedge heads feature an exclusive combustion chamber design.The patented 61cc chambers feature rotated intake and exhaust valves moved over the center of the cylinder bores. As a result of optimizing the valve locations, valve angles, and combustion chamber shape, the Twisted Wedge heads use stock height exhaust ports without power loss.
The heads are machined for 2.02" intake/1.60" exhaust valves to build top-end power without sacrificing bottom-end torque. They don’t require flycut pistons for use with cams up to the specifications listed—no other 2.02"-valved head for small block Ford offers these features!
It doest say anywhere in there that the design was to prevent hitting... I dunno any insight anyone?
