On a stock 1970 440-6, are there supposed to be any spark plug heat shields on the passenger side?

Thanks 750-H2, that's what I had thought too.
I just got my car back from being restored by Alan Gallant and he said the passenger side is not supposed to have any.
Are you certain or is Alan wrong?

Near the bottom of the page pt # PWS 01

It actually only shields the very rear most wire..

I've always felt Alan builds a damn nice car, but not a concours type build.. If thats what you want there are builders who specialize in those sort of cars but you may want to look into getting your wallet equipped with a cooling system....

Yes I am sure that #6 and #8 have a heat shield. It is a one piece shield that protects both plugs. Factory part # 2951347

That's great!!!
I imagine you had some quick rides on that!!!

Only have the keys to that bike of mine left.
I rode it without the right carb K&N and destroyed that piston and cylinder.

Last saw a 750 down here in Houston about a year ago.

Yes. The Nos. 6 and 8 spark plug wires have heat shields.

That is what I remembered... But then I went to the Hoffman site & he didn't list the shield for 6&8 just the single plug... Well I'm tearing down my car which was built 20 years ago & at the time it was very original.... I photographed the original engine details & recreated everything to a ridiculously high level, stencilled logos on hoses, reproduced stamps & markings on everything... Anyway point is I took photos then & duplicated everything so this was a reference level resto at the time & since then I've driven the crap out of it... Well theres a shield on 6&8 plus a shield on 7.... There is a plug wire bracket on the driver side third head bolt from the front...  And both front exhaust studs...
