Suggestions for new design Aluminum Mopar SB clean slate (kind of) cylinder heads
Girdles are for high rpm and/or very aggressive and high lifting cam lobes. They are, IMO, not a big deal. Considering BPE is concentrate on a street head, I think, IMO, it’s really a moot issue point to quibble about.
Again, IMO, Pittsburghracer shows this with Edelbrock’s street head. It is a replacement style head. He does very well with it and he reminded what it is as well as what it isn’t. It isn’t a race head.
If BPE makes an aluminum Magnum head with mild enhanced features like the Edelbrock head(s) Magnum & LA, it’ll be great. For me the home run will come when it can be ported out better than what a Edelbrock head can be done to.
For street bound cars, the Edelbrock head is very good and the Trick Flow is for a heavier hitting engine and car. If you need to step up beyond a TF head, your really looking at a race head now aren’t we and that’s beyond the scope of the question at hand by Johnnymac.
So what’s the point of talking about such a head?
It’s not coming.
