Are these intake manifolds really worth it can you tell the difference without having one as opposed to putting one on or is it just better for the motor in the long run what are the benefits

The main benefit is less chance of the isolator warping and causing an air leak. I put an alloy intake manifold on my engine last year after running the phenolic intake for several years. I noticed the aluminum one was leaking so retorqued it and it stayed sealed after that. I also suspect that on a hot day last summer the aluminum manifold transferred too much heat to the carb causing the motor to kill during a race heat. I built a new engine for this season and am trying the RB Innovations manifold with heat sinks and diaphragm filter, we'll see how it does in the heat of the mid summer.
Yep, on my winter rebuild I used a very thin bead of Yamabond on all the joints. I don't expect any more issues.Did you use the teflon gaskets with it?
I have em on mine and never had a problem
I was running shreadstacks but I switched over to Turtle Racing air boxes for this year, all set for reed valve mills next winter.THe Rb Innovations one is legit. It has enough heat sink to dissipate heat away from the carb. Also the shreadstack inclined manifolds is the same thing as far as warpage. My 5b stock airfilter manifold i can push down and see air space through it when its mounted. Pretty much think of it as insurance as nothing will warp letting dirt in. Also the smooth aluminum cnc work will improve airflow...
