Default trick flow 235 on 402ls2 questions

Will the trickflow 235 head bolt on a 402. 4inch stroke 4 inch bore?

How do people like the 235 trickflow heads? Strong heads should be able to handle very high boost psi?

Any one know of other engine combs running the 235 heads. Link or info?

Would there be added flow with 4.1 bore. Would it be enough to really make a change. It's going on a supercharged engine so thinking I don't have to worry about shouding to much right? Would rather have the thicker cylinder walls.

I have them on my 402. They work well and yes they would work better on a 4.1" bore.

yep we installed a set of TEA prepped 235 heads on an SLP 402 a customer brought to us for installation. Made 512rwhp with 240/244 cam. (M6)

for a comparison, same SLP 402 shortblock, again customer brought to us, with stock L92 heads and I think 236/242 made 465rwhp (M6)

both cars Fbodies
