Do you already have the heads? L92's are awfully big for a truck that heavy if you don't have a 6 spd trans and vvt. If it were up to me I would be tunning some mild ported 317 or 243's and a smaller tight lsa cam. 212/218 ish on a 108-110 lsa. For the L92's Id definitely go the thinner gaskets and you are going to be 212/221, 108-110 lsa area. The L92's like more exh duration especially on the smaller cams.

It's pretty good but she drinks oil! Driving about 230 miles cost me a quart of M1 10W30 and that was at 65 mph.
My neighbor at work offered to help me find and install a low miler from a salvage yard in San Antonio. After this trip I may give up the cam and head back to stock, sort of.

It seems Lunati puts more exh duration in the ls1/l92 cams.
I'm on the fence on these two
