Bolts For Riva Non-Girdled Head?

[Yohns Kustom Fabrikation]

My stock bolts are to short for my new head. Has anyone else had this problem? What length bolt should I be looking for and from where? McMaster?

Anyone?

Yes, the stock bolts are indeed a bit too short for the Riva non-girdled head.
I've had that exact problem before.
I ended up ordering slightly longer stainless steel allen head bolts from McMasterCarr.

Can't use the stock headbolts! I have a set at the shop I can measure for you.
I think we might even have a set of S.S. allen head bolts, call or email shop and I'll look to see what we have...Chuck
