Edelbrock Heads for 318

"BJR Some Great Advice Again I Hear What Your saying about the 1.88 int Valve I Have Compared with the Early 68/71 Teen Valve & They are more of a Tulip.
Moper I can Understand you use of the Stainless Performance Valve for this Very Reason,& Yes I Had a Laugh too about the Swirl Polish Jobbies as I To think this Really is just a Good Look thing than a Power Inhancer.
Do you think If I Was to step up this Motor Later on to a Hotter Set up Would Now Be a Good Time to Fit Stainless Valves & Go to 1.88int/1.60ex or just Leave & Maybe just do the Exhausts First as they seem to be the Ones that Have Sunken with age??
Cuda 66 On this Forum Has one Hell of Hot Setup for a Teen to Run 11.6s But By the Look of the Combo Post I Amazed that it still Runs a 1.58ex He Has Increased the Intakes Though to 1.88s But still to run a Racer Brown cam ST 21 specs @ 50-224/ 520 full lift Thats a Lot of Lift for a Small Ex Valve,Mind You the Rest of the Combo Suits His Idea of What he Wanted to Do...
