		| RE: Largest valve set for C4AE heads on a 390 bore |

		I'll just jump in here with an opinion and maybe get the ball rolling for you.    You're okay with the 1.66 exhaust valve.   That's the low-riser/Cobra Jet size and should be no problems with a .030 over 390.   But now that big intake valve at 2.19 might be a problem for your cylinder.  That's the medium riser intake valve that has no problem opening and closing with a 427 size cylinder.   Are these heads already done with these valves?  I've heard of these 2.19 Intake being cut down to 2.15 and that works in a 4.13 (428) bore.  But if these C4AE-Gs are already done with the 2.19s, well that does somewhat limit you in what you bolt these heads onto.
  So now I need help with my contrived answer.  There are guys here who know exactly if this'll work.  |
