Studs..

Am I correct in thinking that the three studs screwing into the cylinder head face(mating with barrel) are 3/8 BSF
And the 4 cap head screws holding inlet manifolds to cylinder head are 5/16 BSF

Many thanks

They're 5/16" x 18 BSW (7/32 Allen key, although often mistaken/replaced with 5/16" x 18 UNC, 1/4 Allen key).

Top Man thank you
