Being that dome is made for the Edelbrock heads it looks like it's going to be a really close fit for a TFS head when comparing the two. It doesn't specify for which Edelbrock head it is made for, it would be a good idea to talk to tech support for their input on what it's designed to be used for.

Spoke to previous owner of the pistons other day and when he brought the engine that piston were in they had indy s.r heads on. I've googled indy s.r heads and they had 75cc combustion Chambers so am I right in thinking I will be ok with trick flow 240 heads as they are 78cc C.C
