BBC head gasket ???
Two fold question, first the motor- It is a fresh never fired 461 CI 454 based engine (8.2:1 Comp. KB hypers. I do not want to hear about how I should have chosen different pistons, too late damage is done and the money is spent, I will not go back into the block again.) Assembled w stock 049 heads but never even installed, now mid stream I had a set of 781's (shaved .030 to increase Comp) + redone w 1.88 + 2.19 valves, pocket ported, triple valve springs, Tit. retainers, 10 deg locks w PC seals. Both block and heads are flat and I am using ARP Head studs. The engine was assembled B4 w Felpro 8180PT2 Head gaskets-.038 compressed.
A- I have a new set of steel shim head gaskets-Mr Gasket # 1131-.020 compressed thickness, Should I spray these w copper coat gasket sealer?
B- Can the 8180PT2 Felpros be reused if already torked down but never fired? spray those first?
C- Just say Sc_w it and buy an altogether new set? If so, which? keeping in mind I want no more than .038 compressed thickness preferably closer to .020
Intended use- Strictly street w MAYBE 1-2 strip runs in a year just to see how it does, It is going into a 55 chevy BA Wgn. My last BBC car and now that i am disabled a wgn makde sense to me (to carry my scooter to shows/runs)You will note that alot of what I have done is over kill , I know, but I had this all new stuff on the shelf and wanted to use it all up rather than buy more new.Last edited by Dgas56; 12-21-2009 at 05:50 PM.

Thanks guys! It's been a long road. Fun doing finishing work for sure. Getting the dash ready for paint and some interior trim. Have to do some finish work on the aluminum headliner before...
