Looking for a solid lift cam that's really similar to my XE274H in lift (.325/.327) but everything I am finding is much larger & ends up being .550+ with a 1:5 rockers. I have flat tops w/no valve reliefs so I don't have a lot of room.

the lift is not so much what causes piston to valve clearance problems, cam timing & long duration is the main culprit.

Little more info, what I've got right now is
Cam - Comp XE274H 274/286 duration 230/236 @ 0.50 duration .488/.491 lift(advertised) .510/.523 lift(actual w/1.6:1 crane ductile rockers) .325/.327 lobe lift LS of 110* Intake CL 106* 3 bolt timing gear
Installed @ 0 & I checked with dial indicator & it checked out as spot on.
Block has been decked .0125.
I have 0.085 piston to valve clearance.
Looking for a similar set-up, looking to take it to 6,500 rpm.
I know with a solid there is lash introduced which will increase the lobe size slightly I can get away with.
Not going roller, just a simple solid & want as much lift as I can but it's already in the car & I don't want to pull a head to check my clearances. Just trying to do it with the info I already know on the car.
I didn't know if there were some not so mainstream cam mfgs that would be good to look into for this set-up. The comp XE is really noisy for a hyd cam so I may as well have something that is good on the top end since I now have adjustable rockers.
