valve cover issue

I recently droped a built 454 engine into my 68 k2500 and the edelbrock elite valve covers are posing a clearance issue





I have 1.8 ratio harland sharp rocker arms and I need shortet tall valve covers that will clear these

the covers are right against the firewall and the booster is really close
any one know of any covers that will fit?
the truck also originaly had a v-6 as well

this might be a dumb question but can you put a big block in the 6 cyl position like you can with a small block? maybe thats the problem, its sitting too far back, or maybe im just an idiot lol

oh it had a 402 a few months back, so it should fit the option of pulling everything forward 1/4" does exist but if i can leave everything as is I would be much happier (the exhaust will be fine ect)
I thought about taking a hammer to the firewall but i don't want to go there, would rather do it right

I know some one else has to be out there with a bbc and roller rockers

it's hard to tell which booster you have. the 1/2 ton had a larger diameter than the 3/4 ton ones (i think)

I have the same problem. Went with a short Billet Specialties set from Summit Racing.

Cleared my 1.8 roller rockers (barely)

A body lift...or more of a body lift would solve this problem.

I thought about that. Decided that it would look seriously goofy on a 2wd truck.

I am still thinking about a drop for mine, but don't want to lose tow/haul capacity.

I am really thinking about using ORD's 1" aluminum spacers that would solve the boster and passenger side issue but the drivers side firewall would still be a prob, it would only need ~ 1/8" or so to clearance to get the needed room

I could just buy the pucs

I went through this problem with my smallblock, I first installed PT # 4249 *(B) Tall ones and I had firewall clearance problems so returned them for PT # 4248 (B) Low ones and no problems. However I just checked Edelbrocks website and they don't make the low ones for a BB only yours (PT # 4280 Tall) wonder why?

well I put the chrome (ick) valvecovers that where on the prev eng and they bolted down fine, I still need to turn it over and feel to see if the rockers are hitting I may try the billit specialty ones

does anyone have any exp with the alumnum spacers for VC?

also I think it would be fine if the top of the vc was curved not a right angle
