Fireball ran way more than 1400 flywheel with a 4 bolt head, but I agree a 6 bolt AFR head would be a nice option to have.

BUT....if we implement it across the entire line and include it in our future rect port offerings it starts to become more palatable regarding the tooling and foundry costs involved.

So what are AFRs plans for a rect. port heads? Hopefully something with a smaller than stock intakeport(Like MAST did) to keep volosities(SP) up.

That was also with a double o ring which, if you talk to Fireball the sleeve/block failed from the grooves.

I want to try, to get away with a 6 bolt head with a single o ring so that we can keep the block/deck strength as much as possible.
