opinion comp magnum roller.

Use a good valvespring and I don't think you will have to worry about eating springs up with street miles.

I am putting a crower solid roller with .680 lift at the valve into my street/strip motor that see's lots of miles...Good valvesprings and lifters will be key, as well as rockers and pushrods

Sure...never hurts to get specific though

Thanks for the advice and that video sounds good!

Maybe i should look for alitle more lift while im at it then,have looked at a cranecam aswell,but not sure it would be worth all the extra work setting up the heads for more lift thought.. the crane cam i have looked at is a 260/266@ .050 and .630" lift but would require cutting down the guides and cut the springpockets aswell(not sure if i would run into oilingisues also at that point around the lifters even with the complifters would probably need to figure out a good way of checking that). the man who ported my heads years ago said no real point in going past about .600" lift with these heads,the headsbasic design is basicly junk in his opinion trying to get them to flow smooth at higher lifts,and i trust him(works on prostock cars) and .630" lift in the catalog would be just under .600 at the valve with the crappy pushrodangles,alitle flex and the lash.

sorry for the long post.
to much going on in my head with this camchoice.
