Hello,

for my 305 Corvette 1980 C3 engine I got new bare EngineQuest heads CH305A, Intake Runner Volume 170 cc, Comb. Chamber Volume 58cc,
Intake Valve 1.94, Exhaust Valve 1.50

regarding the cam upgrade I'm thinking about:

a.)

Comp Cams XE262H-10 "Xtreme Energy" hydraulic flat tappet cam. 218/224 duration @ 0.050, .462/.469 lift,


or


b.)

Lunati #638-60101LK
Voodoo Camshafts
Lift: .454''/.468''
Duration: 256°/262°
RPM Range: 1000-5500


Now to my question:

what brand of valves should I purchase ? what lenght ? stock length or longer ? anything which is important which I should pay attention to ?

springs, etc.. are comming with the kits of comp cams or Lunati.


I'm looking for your well appreciated input.


best regards from Germany

305A is not correct for you engine, the catalogue says it's for 1996 to 2000, did you mean 350A?

no - it is the 305 EQ Vortec head which gonna fit as well on my 305 engine.

I have just to install as well a vortec intake.
