Legal Heads for SS/modified

The Aluminum heads would be legal in SS/BS.

Can run SS/BS with either cylinder head, or run SS/AS with the SB2.2.
Can also run SS/AM thru SS/FM with both heads.
Canted valve allowed also in SS/AM and SS/BM.
SB2.2 is a splayed valved head, not canted.

I think the 2016 Div 4 SS champ ran a small cu in SB.2 engine in SS/BS.
Two sets of headers came with the car. Looks like a 15-18 deg set and an SB.2 set.

SB2 is a canted, not splayed.

He is asking about the SB2.2, not the SB2.

SB2 valve angles are 12° x 4° Intake and 8° x 0° Exhaust and considered Canted.

The SB2.2 valve angles are 11° x 4° Intake and 8° x 0° Exhaust and considered Splayed with all the intake ports pointing towards the center of the cylinder head.

The 8° Exhaust valve angles towards the intake manifold just like a normal wedge cylinder head.

Thanks, did not know that!

The way I read the new Head rules is that any aftermarket head is legal in SS Modified. Doesn't need to be factory part number any more.
some CFE splayed valve in SS/AS or AJ 18 degree in SS/BS??
