if you got a static 10.5:1 comp thats some nice pistons, no matter if you had .038 gasket, advance youre cam up on install at least +4... ("+6 even") being 110 lobe sep on 273 you want to get youre torque band come in pushing A full body, specially if auto' obviously 318-360 are more forgiving (107-108 ls good for drag accel launch), once off the line she will have some sting, good for open street/track race day, and sound like a track car not a harleyLOL (as mine does) and she'll drink 98octane ;)

if using standard valve train (that you should) get d moly -.100'retainers so can fit the spring in without bind and scallop rockers so they dont hit (and reposition oil galley''), you may get away with LT1/chevy brown spring for this too??, unless you are hitting over 7000rpm on reg basis, do doubles!
