I'm shopping for a set right now and would love to hear any feedback on your experience with them, good or bad. I'm planning on getting the 76cc (427) heads because I'm using the TRW L2245f .060 over pistons in a '69 428 CJ motor and I like the idea of a slightly lower compression ratio that the 76cc heads will get me vs. the more standard 72cc Edelbrock heads. I figure the combination should get me around 9.7 compression ratio vs. just over 10.0 with the 72cc heads. I figure the 439 cubic inches that the .060 over bore will get me coupled with a low riser, dual quad (600cfm carbs) set up and a reasonable cam for the street (Comp Cams 270H or 280H?) should be make up for a couple of fewer points on the compression ratio?
Other then reducing the
oil accumulation problem in the heads by opening the drains a little (or alternatively reducing the incoming
oil supply to the heads- I think Gessford sells some plugs) I haven't heard any bad news on the heads. Thoughts? Feedback?
