Yeah.

:agree: Always check with a solid lifter,if you're good to go on PVC that way,you'll definately be safe with the hydraulic ones.What are the length on your pushrods,are you using stockers,or custom length?

He'll need longer pushrods for those TW heads; somewhere around 6.700".

That's what I was thinking,and if he used the stockers to check the PTV................

i am using 6.550 length pushrods and stockers are 6.25. i aint to teribbly worried about the length i made sure the lifters were pumped up real good and used the new pushrods and rocker arms to check everything and didnt use a head gasket so that gasket will give it just a little more clearance.

You need to re check your pushrod length.

Ive put on many sets of twisted wedge heads and used 6.700's on every one of them

well my rocker arms are touching almost middle and a little closer to the intake side. i am using the heads and pushrods that came off my buddies (88scgt) dads 347 that made 663 hp at 4800 before it broke the block and everything looks good.

Have fun with it

Ouch, I take it you have never run any TW heads before. I have owned several sets and can see clearly what your not so distant future holds.
