everything i have seen says yes indeed a side-oiler block and medium riser heads
the tunnel port would have been an awesome (potential choice) as the 302 tunnel port head was done for le man type races and not drag racing. the high riser (needs a much higher hood - ie the big bubble on the 427 Thunderbolt ford factory drag car)
most dont know that the cammer was also a hemi as well
as in single overhead camshaft hemispherical combustion chamber - that incredibly long cam chain was extremly problematic
