What do you guys really like on the TF270 heads?

Harland Sharps made for the TF270 style heads.

T&D is the best. I tested everything that was available and T&D is the only one I'd use on a serious engine that needs to go round after round.

my street car went 9.50 using Harland Sharp. I think with any part you buy you need to check everything. Your cylinder heads are a very critical part. Everything has to work together to include the correct valve spring for the camshaft, locks and retainers, installed height on the springs and one really important item is how the rocker rolls across the valve. T & D has a nice set also. Birdtracker

I have a set of RAS rockers for my 270s.
Never seen or heard of them until AndyF used them on a motor.

RAS rocker arms are very, very nice. I run them on my Coronet since it is a street engine. Can't beat a steel rocker arm for the street. But RAS has been sold a few times and I have no idea how good their stuff is these days. 30 years ago they were the best of the best.

My last two dealings with the new owners and Gary when he took the company back where bad
I've never had a problem with Harland Sharp in over 40 yrs. of buying and using their products.
I do have four sets of Speed Masters I want to try but nothing installed yet.
I have also used several sets of Comp Cams Stainless steel rocker arms and they have work well so far in the last two years They fit under stock covers also

I’ll second the T/D rockers. They are expensive, but worth the money.

I bought the Harland Sharps for my set of TF heads. Seconding Mark's suggestion, there are two versions of their non-offset rocker for stock heads, the "KE" version for the Edelbrocks are are the ones the cylinder head was designed for.

I found that the best valve springs for my combination (won't work with all combinations) was the Comp conicals. Very lightweight and less susceptible to harmonic frequency issues. The conicals work well with the T&D rocker arms.

I like my Crane gold 1.5s . Fit like they are made for them . Been on iron , Stealth and now the 270s . Thousands of miles and passes . And yes i only have run flat tappet cams
