Mike T is a very smart fella if he says it's a non issue then I wouldn't worry,..he certainly wont release a part that's going to hurt his biz or rep,..intentionally,..the alignment deal is no problem with the moderate spring psi these 350s are going to see and the limited rpm and usage overall,...unless you plan on driving it every day,...running 7500+ rpm and the associated spring psi to do so I cant see it being an issue jmo
The beauty of shaft mount rockers is that they run flat across the tip of the vale, unlike a Chevy setup which will want to pivot. The valve should spin while running so there won't be an issue. We'll work up a procedure to correct the offset for those who really want to. If it weren't for the fact that we're going to use my rockers to figure that out, I'd run them with the offset without hesitation. Bare castings are $1650, assemblies are $2800 Notes These heads require the use of a TA 1128AL (Head Bolt Kit) or TA 1133AL (Head Stud Kit). If you already own a TA 1128 or TA 1133, you need to purchase Four (4) replacement bolts/studs (they are longer) to upgrade your kit to an Aluminum Head version. These heads require 5.160” long valves. You CAN NOT use valves from 350 iron heads. Correct valves are available from TA Performance TA 1082 (1.94” Intake Valve) TA 1083 (2.02 Intake Valve), TA 1092 (1.60” Exhaust Valve). When using roller rockers, the exhaust rocker will not sit directly over the exhaust valve, it will be off to the side. This is normal, due to the exhaust valve being moved from the factory location to allow the use of a larger intake valve. If you want to correct the exhaust rocker location, please call and speak with one of our techs.
Unfortunately for me, a 350 is a poor choice for an MGB, the 300 or even the 455 make more sense. However, I'm saving up to buy a set of the Rover heads this fall to go on my stroker 300 build. I only wish they'd been able to get the same results with the breathing on those heads as what they did with the 350 heads but I've never heard anything saying that they were even close to being comparable. I don't have the numbers so I don't know, but it's a little disappointing. Jim
