[QUOTE=Bumpstick]An interesting article for sure... Might also be the reason I have 5 sets of large ovals (781`s & 049`s and some real cool semi-closed large ovals)

But just something to point out... The standard installed height of the valves in an oval port head is 1.880 which limits the spring you can use and the the lift considering coil bind, also the guides have to be machined to use anything over a .550 lift cam... Will cost more to modify for the .100 lift but still darn good heads for street/strip apps...

Good point,, The cam I ordered is the Comp,414 nitrus/ blower with 566 in. and 575 Ex.. hyd roller,, we were concerned about piston / valve clearance,,
the 411 comp cam [ nitrous/ blower is 537 and 541,, would this be a better choice,,?? Bill
