Mike,
The AERA www.aera.org has a list of rubber seals to replace rope seals in various engines. They show that the seal from a Ford 200 will work on the 455 Buick. The Fel Pro part number is BS30135 The only thing you need to be careful of when replacing rope seals with rubber type ones is that sometimes the "groove" in the block and cap is not as nicely machined as you would like it to be. Make sure to check the fit of the seal very carefully. Also a good idea to polish the grooved area where the seal rides. You dont need to remove the grooves, but make sure the surface is pretty smooth.

Hope this helps,

Dean, The rear main seal from the Ford 6 cyl. CarQuest(Victor) #JV730p works, Also you can replace the front cover rope seal with a National Seal #450446. You have to drive the inner rope seal retention ring out of the front cover to install . As far as oil pump relief springs I've used both the stock and stage1 spring, if you only have the stock spring you can add a round head sheet metal screw (same O.D. as spring) between spring and cover nut to boost oil pressure. TA Performance also make's an adjustable relief valve cover nut so you adjust your oil pressure. I run my oil pressure line out the left rear lifter gallery plug : oil pressure I have is 60 psi cold - 20+psi hot 30w conventional (brake-in runs) at idle and 10lbs less with 20w synthetic (race).

One thing I found on ours was after you cut the heads to min. spec - the dowel pins would bottom out and not allow the head to sit flush. Make sure without the HEAD GASKET the head sits flush on deck. Ours also loved a 3" X-pipe, talk about snappy. Good luck!

I have used both steel and alu none made a differance on the dyno, they all will punch the pushrod end out once in a while
