Roller rocker alert

[Sardonicus]

Dont presume ever it OK just doing some final checks with my bespoke TVR rocker covers that I had heard clear roller rocker (well Yella Terra's) WELL THEY DON'T just a heads up there are 2 places that need to be relieved in each RC 1st, just a heads up I would hate someone to ruin their push-rods or worse still have a valve stay open and clout a piston crown

I've got YT roller rockers & they fit fine. I've got them under the black TVR logo'ed rocker covers.

mine fit fine under John Redmond covers!

[Pupp]

My TVR cast covers clear my YTs ok - it is close but they don't interfere

Well mine dont and I may be running a bit more lift .518" like I said worth checking you will find if yours clear it will still be marginal IMO

To be fair - that is a lot of lift.

Guess you have either a M248 or M256.

Hopefully you used the thick rubber gaskets and not the cork.

Mine need a bit of a wriggle to drop in place Simon but do clear, and that's on a big cam

I also have shimmed & spacered (is that a word? ) rocker shafts rather than springs to put the roller tips over the valve stem centers so probably made things worse anyway it was no biggy 10 minutes with a ally burr got things opened up just a warning even our resident Spend looks like he had the same issue on the same centre 2 rocker arms, although these are a different brand of RR's (knew I had seen this somewhere before) ...............................

I had to fit spacers, if you make sure they a water jet cut, not laser cut ones

Would I see any difference with roller rockers on my engine ?

No, you can't see them Daz, they are hidden under the covers
