103 kit info needed

looking into a 103 build. want to make a reliable 100hp/100tq. this should be easily done. but more is always better. i am sure some of you guys have some "piece together" kits that run great. i am not scared of getting some head work done. as i think it is a must to get the best out of this combo. what are some of the aftermarket company that make a killer kit??? i think i will go ahead a do the compression releases too (manual)...budgit 2500-3000

hey QUIKLUV, check out harleys kit part #27544-10. i'm really sold on it, the kit comes with the 259-E cams, 10.75 to 1 compression ratio forged pistons, all sorts of other goodies. my 103 runs like a pissed off gorilla and has been very reliable. several other guys in the forum are using the same kit and have had great results as well. the manual compression releases while it's torn down is great, along with the s.e. compensator.

Manual CR

Is there a reason you would want to do it manually?

Thanks

i am kinda on the fence about the auto CR. the way i look at it is the manual will always work.

anyone else have input?

Me too! the parts are sittin here in my livingroom.just pieced together this stuff from ebay(came in boxes from harley dealers).did some homework ,259 cams are as much lift as mcr heads can handle,shouldnt need new rockers but am replaceing the inner cam bearing,and lifters(stock) while im there.Shouldnt need bigger throttle body/injectors(stock),air(already se ac),im stuck with using stock head gasket for the most part with perfict fit pr cause i dont want to deal with adjustable ones. dont have to deal with sending heads out or worrying about valves..ect with 30 k miles on my stockers using new heads.

ive searched and searched for a 1000 hours and have seen nothin wrong with this build ,259 cams like higher compression so this is a tender area,,,we are looking at about 10:1 actual compression or less?...will this be good enough for these cams? should i have used a higher compression piston(22144-08B)? vs flat top.should I say fugg it and use adjustable pr w/cometic 0.03 head gasket? these are my main concerns ????????but time is running out.Maybe its better to run comppression this way for ping factor? btw just added medium spring on clutch and se comp aswell.also replaceing all the bolts with crome while im there(even tranny).the extras(optional),items and tools total 500$

I'm thinking about a 103" build also, jugs bored localy, SE cast pistons, TW 6-6, 555 or Andrews 54H cams, .030 Cometic head gaskets, heads by www.bigboyzheadporting.com w/ MCR's. Already have Rinehart True Duals, SE a/c & PCV w/Autotune. Hoping for about 100/100 also. ????
