Dual pattern cam makes up for poor exhaust port. Surely it won’t hurt. Oem heads are done by .440 lift. The comp 260 is another good grind. 212/212-.440
looking for feedback on solid flat tapper vale springs. I currently run beehive 365 ci 135/335 on a 238/238 .560 lift but it doesn’t pull past 5400. Stepping up to a 12:1 414 this season 272/280 .590 any suggestions.
I run early 318 heads with small valves 208/214 delta cam, and 9:1 in a w100 @ 4700 ft. 800 Rochester on a stock spread-bore. Save your money. Pulls from the bottom and hold 85on the freeway with ease 29” tire 3:55. 302 heads aren’t magic.
I have ran the Mr. Gaskets with aluminum heads with out issue on my 360. My other car has the Holley's I believe that are a bit thicker, .05 with 11.5:1 and 308 castings.
