Small block TrickFlow heads part 1

Ok one thing I forgot to mention the other day my favorite set of intake gaskets that I usually have 5-10 sets laying around which is Edelbrock 7276 fits the intake face perfectly. First thing I found out today after checking intake and exhaust calibration was don’t expect to use the regular 1/2 inch National Fine nuts on the outside bolt holes. These will require the smaller 12 point head nuts. View attachment 1715800258

Their instructions state that the head bolts or studs/nuts kits they list as items being “required” A need for the flanged reduced bolt head (9/16” hex) or the smaller 12-point nuts for tool clearance is obvious, but I never checked to see if the bolt lengths were the same as the factory bolts. Have you checked the lengths of all the studs your using? I assume they are the correct lengths and it’s just the reduced bolt head/nut size that’s different.
