Wize In my E-headed 360 i,m running a Lunati 60433 solid roller. 249/255@50 .585/.600 lift., and Crane 69790 pushrods. The pushrods are just brushing the heads, and even though its gone 7000 with no issues(so far) i,m a little nervous about. Going to pull the heads off and do a little clearancing.  Glenn

Sometimes 1.6 rockers help the problem. If you look at the picture on post from djvcuda, with the solid roller and 1.5 rockers he has it marked where the pushrod hit the top side of hole. A 1.6 rocker arm will pull the pushrod down away from the top side of hole.

I'm running 1.5's....for now but will clearence for worst case...any pics of how much you cleared? Heads were ported by Ryan J so the Pushrod pinch won't be touched, I've run tubes before but not worth it for this build...I'm already crazy enough putting this much motor in this thing

Quick update, I was over at my buddy Hollis Page's (HP engines) and while he was changing out my springs for the new solid I mocked up the fit on one of his several small block mopar shortblocks. it looks like the bottom of the deck side and the top of the spring side need to be worked the most. Ryans stage 2 port job only leaves about .070 of wall thickness against the intake ports so you gotta be judicious, I'm going to use 3/8" pushrods so I'll probably rough cut with a 15/32 bit and then blend with a dremel. What I suspected and learned from the mock-up is that the angle is more severe using the taller solid roller than running a flat tappet, so the potential contact area will be overall less surface area but at a more severe angle. (i.e. less parallel). Another shout-out to Hollis Page, congrats to HP Engines in Norwood, NC for being one of the 8 selected finalists competing in the upcoming Mopar Muscle Big Block engine challenge, we were comparing some notes and ideas yesterday...watch out for them CAROLINA BOYZ!! They can sure bring the power!!

toddd, Are those 3/8" or 5/16" pushrods? Makes a difference for sure  BTW the 414 Rocky debut at Rockingham may be in jeopardy.....my SB solid roller lifters from Doug Herbert are on back-order. The best laid plans right?

Well i did a quick 'ream job' on them as i described above, I think the clearance should be adequate based on what I'm seeing/hearing. I also just swapped the roller in and degreed it so I'm at the mercy of Mr. Herbert
Check with Howards cams in Michigan, it's the exact same lifter. See if they have a set on the shelf...

Thanks Ryan! I'm gonna give the boys at Doug's place about another week, he said they're made but they're now in the final stager/hardening process before final assembly and hope to have them shortly...Doug Herbert is a local NC shop and they try to do it right by thier customers, I feel pretty good giving them a shot whenever I can, you know help support the local economy whenever/wherever I can. BTW... while we had the valves out to istall the new roller springs....I was admiring the port work.

Finally got my Lifters, mocked up looks like I need a 6.55" 3/8 X .093 effective length with 5/16 ball/cup, When I spun it over to check my P/V (got a mile for .585 Lift 266 @ .050 duration roller (for you 408-416 guys contemplating Mahle Pistons) I used a 5/16 x .123 wall that is about 3/8" short (barely had enough take up on the rocker) but it looks like the 7/16 ream work I did on the E heads will do the trick for a 3/8". Now where is that Manton Vs Smith Bros thread???

I'll open acan of worms here. Using a 5/8 end mill set so that it just takes .005 off the orginal pushrod hole on the port side, bore them out. die gind the pushrod pinch out of the port. Press in a 5/8 od brass tube cut to lenght with some locktight sleeve retainer. You just picked uo at least 15 cfm of air and will have push rod clearnce galore. Exhaust just bore them out.
any pics of this thanks
